DEAD-TIME ELIMINATION FOR VOLTAGE SOURCE INVERTERS


Share

A novel dead-time elimination method is presented in this paper for voltage source inverters. This method is based on decomposing of a generic phase-leg into two basic switching cells, which are configured with a controllable switch in series with an uncontrollable diode. Therefore, dead-time is not needed. In comparison to using expensive current sensors, this method pre­cisely determines the load current direction by detecting which anti-parallel diode conducts in a phase-leg. A low-cost diode-con­duction detector is developed to measure the operating state of the anti-parallel diode. In comparison with complicated compen­sators, this method features simple logic and flexible implementa­tion. This method significantly reduces the output distortion and regains the output RMS value. The principle of the proposed dead-time elimination method is described in detail. Simulation and ex­perimental results are given to demonstrate the validity and fea­tures of this new method.

  1. Introduction

To avoid shoot-though in voltage source inverters (VSI), dead-time, a small interval during which both the upper and lower switches in a phase-leg are off, is introduced into the standard pulse width modulation (PWM) control of VSIs. How­ever, such a blanking time can cause problems such as output waveform distortion and fundamental voltage loss in VSIs, es­pecially when the output voltage is low.

To overcome dead-time effects, most solutions focus on dead-time compensation by introducing complicated PWM compensators and expensive current detection hardware. In practice, the dead-time varies with the gate drive path propa­gation delay, device characteristics and output current, as well as temperature, which makes the compensation less effective, especially at low output current, low frequency, and zero current crossing. Several switching strategies for PWM power converters have been proposed to minimize the dead-time effect. A dead-time minimization algorithm was also discussed earlier to improve the inverter output performance. A phase-leg configu­ration topology proposed prevented shoot through. However, an additional diode in series in the phase-leg increases complexity and causes more loss in the inverter. Also, this phase-leg configuration is not suitable for high-power inverters because the upper device gate turn-off voltage is reversely clamped by a diode turn on voltage. Such a low voltage, usually less than 2 V, is not enough to ensure that a device is in its off-state during the activation of its complement device.

Protection of Low-Voltage DC Micro-grids


LV dc microgrid is used to interconnect distributed resources and sensitive electronic loads. To ensure reliable operation of the LV dc microgrid, it is important to have a well-functioning protection system. When designing an LV dc microgrid protection system, knowledge from existing dc power systems can be used. However, in most cases, these systems use grid-connected rectifiers with current-limiting capability during dc faults. In contrast, an LV dc microgrid must be connected to an ac grid through converters with bidirectional power flow and, therefore, a different protection-system design is needed. In this paper, the operating principles and technical data of LV dc protection are presented. Furthermore, different fault-detection and grounding methods are discussed. The influence of the selected protection devices and grounding method on an LV dc microgrid is studied through simulations. The results show that it is possible to use available devices to protect such a system.

Attendance Management Using Face Recognition System

The aim of this project is to deal with the problem of face detection in color images. Unlike in face recognition, where the classes to be discriminated are different faces in face detection, the two respective classes are the “Face area” and the “Non face area”. The novel approach to face detection is presented, binarisation rules especially designed for a skin area detection within a image frame.

The process involves Binarisation, localization, training and identification of Human Face.

This project easily extract the human face from any other images. Image segmentation algorithm is used to identify the face from other images.

After recognizing the face, the PC puts the attendance for the particular user. Also it sends signal to the microcontroller through serial port. The microcontroller analyses the signal and operates the door motor through driver section. The microcontroller program is written in assembly language. The microcontroller used is PIC 16F73

In this project, the camera is replaced by CD drive. The face is stored in the CD. As soon as the particular CD is inserted, the software in the PC recognizes the face and sends signal to the microcontroller through serial port. The PC recognizes the face and checks the data with the existing data. If it matches with any data, it puts attendance for the particular user. Also it sends signal to the microcontroller

The microcontroller used in this circuit is PIC16F73. It is a 28 pin IC with three I/O ports. It has inbuilt ADC. According to the signal received from the camera, the values are stored in the RAM of the microcontroller. Accordingly the microcontroller controls the door motor through driver section and relay. The microcontroller program is written in assembly language. The assembly language program is compiled to form “hex” code. The “hex” code is written in the microcontroller using PIC write software with the help of PIC writer.

Bluetooth Energy Meter

Abstract

The word automation brings to mind devices that operate with minimal human intervention. In other words, acting or operating in a manner essentially independent of external influence or control. It finds application in controlling industrial equipments, home appliances, computer peripherals and robots. Bluetooth is a promising new wireless technology, which enables portable devices to form short-range wireless ad hoc networks and is based on a frequency hopping physical layer. Bluetooth is a frequency hopping system, which defines multiple channels for communication (each channel defined by a different frequency hopping sequence). A group of devices sharing a common channel is called a piconet. Each piconet has a master unit, which selects a frequency hopping sequence for the piconet and controls the access to the channel. Other participants of the group known as slave units are synchronized to the hopping sequence of the piconet master

Home and office automation using Bluetooth enabled devices have generated sufficient interest in the networking community. Bluetooth based automation offers flexibility, even when the devices actually present far from the master unit. The commands for the automation unit are given through the software module in PC. From PC the command is given to Bluetooth USB adapter. The Bluetooth USB adapter enables the Bluetooth communication and converts the data into airborne signals. The Bluetooth transceiver has a built-in antenna receives the air borne signals and transfer the data to the embedded controller through serial port. The Bluetooth transceivers can be operated in point-to-point, point-to-multipoint and multipoint-to-multipoint architectures.

The embedded microcontroller is programmed to read the data. The embedded controller is the CPU that decides the operation of the automation unit. The embedded controller used here is 89C51 microcontroller. It is a derivative of 8051 microcontroller whose architecture and instruction set are same as 8051 microcontroller with some additional functionality. Since the controller has the inbuilt peripherals it is called as embedded controller. The embedded controller controls the automation unit as per the commands. Bluetooth based systems are developed to manage proper safeguards to prevent unauthorized leakage of information. Synchronizing data between cell phones, laptops, and PDAs; using cell phones as cordless phones when at home; and connecting PDAs to the office LAN are some of the cumbersome things that are possible with Bluetooth

Design of a Wireless Medical Monitoring System

Design of a Wireless Medical Monitoring System

Abstract

The main aim of this project is used Monitoring Terminal and it can detect the patient's real-time body temperature, heart rate and other physiological informations, and transmit them to the control center.

PURPOSE :

Now days the fast development and popularization of information processing and wireless data transmission technology, the research of wireless Medical Monitoring System has became a hot topic with the help of biomedical sensors. By utilizing the wireless technique to transmit information between medical sensor and monitoring control center, the free space of patients is enlarged, and the efficiency of the modern management of hospitals is improved

DESCRIPTION:

Now a day with the increase of biomedical sensor we are going into this process of detecting the patient's real-time body temperature, heart rate and other physiological information's .Coming to the main core of wireless medical monitoring system is the design of wireless monitoring terminal, and the development of system software. The monitoring terminal generally consists of three modules: the sensor module, the control module, and the wireless communication module. The sensor module is used for acquiring medical information from the outside, and then converts them to digital signals. The control module is often compared to the brain of monitoring terminal, which is in charge of coordinating the task of different modules, controlling the sensors, processing data, and executing communication protocols.

The wireless communication module mainly deals with the wireless transmission of information. Nowadays, there are various kinds of wireless communication protocols. But since the main task of a monitoring terminal is to realize the transmission of signals such as heart rate, body temperature, and calling signals the data traffic is not heavy. Moreover, because the monitoring terminal is worn on patients, which needs to be supplied by battery, it puts a high demand on the reducing of power dissipation of wireless transmission module. Having taken these comprehensive factors into consideration, this paper chooses the ZigBee technology as the wireless communication protocol. ZigBee technology is a shortrange, low-rate, low-power wireless communication technology

TECHNOLOGY:

Zigbee is new wireless technology guided by IEEE 802.15.4 Personal Area Network standard. It is primarily designed for the wide range controlling applications and to replace the existing non-standard technologies. It currently operates in 868 MHz band at a data rate of 20Kbps in Europe, 914MHz band at 40kbps in USA, and the 2.4GHz ISM bands Worldwide at a maximum data-rate of 250kbps. It is used to verify whether user's truncation is possible or not. One of the main advantages of this ZIGBEE communication is that it provides a noise free communication, the amount of noise added in this type of communication is very less compared to the other wireless communications

Hence, by implementing this project the monitoring terminal can precisely check the heart rate and body temperature of patients, and send them to coordinator and then surveillance center through wireless network.

Solar Based Electromagnetic Braking System

The objective of this project is to design the solar based Electromagnetic breaking system using Object sensor for Automobiles. This project is mainly used in Vehicles either two or four wheelers. In this project is used in real time we can avoid so many accidents.

This project is designed by following blocks

• Microcontroller

• Solar panel with battery.

• Object sensor

• Driver circuit

• Relay

• Electromagnetic core

• Breaking system

The object sensor senses the object and gives corresponding signals. These electrical signals are very small mill voltage signal, so it is given to amplifier circuit. The amplifier circuit is constructed with operational amplifier which acts as power amplifier. Then the amplifier signal is given to signal conditioning unit which also constructed with operational amplifier. In this circuit operational amplifier act as comparator and generate the square pulse given to microcontroller. The microcontroller may be ATMEL/PIC/RENESAS/ARM microcontroller. It will work according to our object already we have programmed.

According to the object sensor value, the microcontroller activates the driver circuit as per mentioned in the program. The driver circuit is constructed with transistor which acts as switch to control the relay. The relay output is directly connected to the electromagnetic core which is attached in the breaking system.

Whenever we control the brake, at the time what happens in the system means one of the coil winding is placed around it. It generates the electromotive force and it's fitted with the suitable mechanical set. Likewise when we release the break the force generation will be stopped and the coil winding releases from the mechanical set.

And here some mathematical calculations about the acceleration component information such as motional track and dynamic process will be gotten for this platform

Description:

Any human body motion, from its beginning to the end, the acceleration of every part of the mobile limbs or other parts of human body is keeping changing. If certain motion is repeated, then its acceleration changing regularity is also very also very close. Therefore if a three-axis acceleration sensor is put on some typical point of measured limbs or other body parts, then the three acceleration components X_Y_Z of that typical point in the motion process can be collected accurately.

Then by mathematical calculation about the acceleration components information such as the motional track and dynamic process about that point will be gotten.

From comprehensive analysis of the data gathered about several typical points detailed information about the measured human body motions is obtained so that motion information is digitalized.

This motion information collection platform uses multi-knot internet technology to

TECHNOLOGY:

Micro-Electro-Mechanical Systems (MEMS) is the integration of mechanical elements, sensors, actuators, and electronics on a common silicon substrate through microfabrication technology. While the electronics are fabricated using integrated circuit (IC) process sequences (e.g., CMOS, Bipolar, or BICMOS processes), the micromechanical components are fabricated using compatible "micromachining" processes that selectively etch away parts of the silicon wafer or add new structural layers to form the mechanical and electromechanical devices.

MEMS promises to revolutionize nearly every product category by bringing together silicon-based microelectronics with micromachining technology, making possible the realization of complete systems-on-a-chip . MEMS is an enabling technology allowing the development of smart products, augmenting the computational ability of microelectronics with the perception and control capabilities of micro sensors and micro actuators and expanding the space of possible designs and applications

RESULT:

By this controller we get the information according to motion of the body.

SMS Controlled Industrial Controller

In a process control industry, it is very difficult for a person to be present or to monitors the system continuously. If not, there occurs damage in the whole process industry. In order to view the process continuously and to check the status of the process we are going to use our project “SMS CONTROLLED INDUSTRIAL CONTROLLER”. This project has been implemented in various platforms, now we are going to do this project using LABVIEW Here we can monitor any number of process parameters. The hardware unit consists of all the hardware requirements needed for the process.

This project is implemented by using LABVIEW software to send the message when there prevails any deviation in the process station. Suppose to say, if we are monitoring eight parameters we have to set the limits for all the parameters so that if any parameter value goes out of range then the corresponding message will be sent to the operator indicating there is a deviation in the process.

The parameters like temperature, voltage, speed, current, level, pressure etc. can be measured by using the LABVIEW software. The hardware unit is interfaced with the system using LPT terminal to PC. In our program we have to enable the parallel port mode by setting the appropriate register values to the port. By using ADC configuration using the program, data acquisitions from different channels are performed. Plotting the graphs for these values with respect to time.

If the parameter value goes out of range, then the message is sent to the operator. One mobile is connected to the PC that is having the hardware interface unit and the other one will be with the operator. To send the message to the other user, we have to do the following settings. First of all we have to establish serial communication using VISA card. After setting the serial communication mode, enter the phone number and the message that has to be sent. This will indicate only if there is any deviation in the parameter value. We can also use buzzer to get ON whenever the data's acquired goes out of range by using DIGITAL OUTPUT configuration using the LABVIEW program.

For this we have to out the data as 1 or 0 to ON and OFF the buzzer unit for indication purpose. The hardware unit is interfaced with the PC by accessing the parallel port and the mobile phone is connected with the PC by accessing the serial port. The Speed parameter can be measured and controlled by using DAC configuration in lab view. Initially set the motor speed at a particular rpm by using the above said mode by counting the data from 00 to FF. By using DIGITAL INPUT configuration, count the number of pulses for every five seconds and convert it into rpm. Compare the current speed with the set speed and out the data using DAC configuration and monitor the speed value in the PC through LPT terminal. If the parameter value goes out of range, then the message is sent to the operator
