High-Efficiency AC–AC Power Electronic Converter Applied to Domestic Induction Heating

In the olden days, several AC-AC converter topologies were implemented for simplifying the converter and increasing the efficiency of the converter. This project is designed to implement an induction heating application by using half-bridge series resonant topology, which uses several resonant matrix converters implemented by MOSFET, RB-IGBTs, and IGBT’s.

This system works based on the principle of the generation of a variable magnetic field by means of a planar inductor below a metallic vessel. The mains voltage is rectified by using a power supply and after that, the inverter provides a medium frequency to feed the inductor. This system makes use of IGBT based on the operating frequency range and output range up to 3KW.

Lamp Life Extender by ZVS (Zero Voltage Switching)

The lamp life extender is essential to design and develop a device to increase the life of incandescent lamps. Since the incandescent lamps exhibit low resistance characteristics, therefore, it may lead to damage if it switched at high currents.

The proposed system provides a solution for the failure of random switching of the lamps by engaging a TRIAC in such a way that the lamp remains to switch ‘ON’ as the precise time is controlled after detecting the  Zero-crossing point with respect to the supply-voltage waveforms.

The Hysteresis comparator is used as a compensator for compensating the phase delay of the back EMFs and also, to check the multiple output transitions from noise in the terminal voltages. The rotor position and stator current are easily adjusted and aligned by modulating the pulse width of the switching devices. This project makes use of a microcontroller. Many of the projects are implemented by using the single-chip Dsp controller for Sensorless feasibility and startup techniques.

Design and Control of Single-Phase Switch Mode Boost Rectifier

The project is designed to improve the control technique for raising the efficiency and performance of the single-phase switch-mode rectifiers. In this proposed system, the switch-mode rectifier operates at unity power factor and exhibits negligible harmonics in input current and produces acceptable ripples in the DC bus voltage.

The single phase-switch-mode rectifier comprises a boost converter and auxiliary boost converter. The boost converter is switched at higher frequencies to produce the shape of the input current closure of the sinusoidal voltage for eliminating electromagnetic interference. The auxiliary boost converter operates at a low switching frequency and works as a current course and current deviator for a DC capacitor of the rectifier. The switch-mode rectifier is the best analog control system for boost converters.

Remote AC Power Control by Android Application with LCD Display

This power electronic project defines a way to control AC power to a load by using firing angle control of the Thyristor. The efficiency of this control system is high compared to any other system.

The operation of this system is controlled remotely by using a smartphone or a tablet with the android application with a Graphical User Interface by touchscreen technology. This project comprises of a Zero detector crossing unit which detects the output and fed the result into the microcontroller. By using a Bluetooth device and Android application, the levels of AC power to the load are adjusted.

Industrial Power Control by Integral Cycle Switching without Generating Harmonics

The AC power to loads is given through power electronic devices like thyristors. By controlling the switching of these power electronic devices, the AC power delivered to the load can be controlled. One of the ways is to delay the firing angle of the thyristor. However, this system generates harmonics. Another way is using integral cycle switching where one whole cycle or number of cycles of the AC signal given to the load is eliminated completely. This project designs a system to achieve the control of AC power to loads using the latter method.

Here a zero-crossing detector is used which delivers pulses at every zero crossings of the AC signal. These pulses are fed to the microcontroller. Based on the input from the pushbuttons, the microcontroller is programmed to eliminate the application of a certain number of pulses to the optoisolator which accordingly gives triggering pulses to the Thyristor to make it conduct so as to apply AC power to the load. For example, by eliminating the application of one pulse, one cycle of the AC signal is completely eliminated.

UPFC Related Display of LAG and LEAD Power Factor

Generally, for any electrical load like a lamp, a choke is used in series. However, this introduces a lag in the current compared to the voltage and this leads to more consumption of electrical units. This can be compensated by improving the power factor.

This is achieved by using a capacitive load in parallel with the inductive load to compensate for the lagging current and thus the power factor can be improved to achieve a value of unity. This project defines a way to calculate the power factor of the AC signal applied to the load and accordingly thyristors connected in back-to-back connection are used to bring capacitors across the inductive load.

Two zero crossing detectors are used- one to get zero-crossing pulses for the voltage signal and the other to get zero-crossing pulses for the current signal. These pulses are fed to the microcontroller and the time between the pulses is calculated. This time is proportional to the power factor. Thus the power factor value is displayed on the LCD display.

As the current lags behind the voltage, the microcontroller gives appropriate signals to the OPTO isolators to drive the respective SCRs connected in back to back connection. A pair of back to back connected SCRs is used to bring each capacitor across the inductive load.

FACTS(Flexible AC transmission) by TSR(Thyristor Switched Reactor)

Flexible AC transmission is essential to achieve the delivery of a maximum amount of source power to the load. This is achieved by ensuring the power factor to be at unity. However, the presence of shunt capacitors or shunt inductors across the transmission line causes a change in the power factor. For instance, the presence of shunt capacitors amplifies the voltage and as a result, the voltage at the load is more than the source voltage.

To compensate for this inductive loads are to be used which are switched using thyristors connected back to back. This project defines a way to achieve the same by using a Thyristor switched reactor to compensate for the capacitive load. Two zero crossing detectors are used to produce pulses for every zero crossings of the current signal and voltage signal respectively.

The time difference between the applications of these pulses to the microcontroller is detected and the power factor proportional to this time difference is displayed on the LCD display. Based on this timing difference, the microcontroller accordingly delivers pulses to the OPTO- isolators to drive the back to back connected SCRs to bring the reactive load or the inductor in series with the load.


This project defines a way to achieve flexible AC transmission by using thyristor switched capacitors. The capacitors are connected in shunt across the load to compensate for the lagging power factor due to the presence of inductive load.

The zero-crossing detectors are used to produce pulses for every zero crossings of voltage and current signal respectively and these pulses are fed to the microcontroller. The time difference between the applications of these pulses is calculated and it is proportional to the power factor. As the power factor is less than unity, the microcontroller delivers pulses to each pair of optoisolator to trigger each back to connected SCRs to bring each capacitor across the load until the power factor reaches unity. The power factor value is displayed on the LCD.

Space Vector Pulse Width Modulation

Three-phase supply can be derived from single-phase supply by first converting the single-phase AC signal to DC and then converting this DC signal to a three-phase AC signal using MOSFET switches and bridge inverter.

Cyclo Converters using Thyristors

This project defines a way to achieve the speed control of induction motor by supply AC voltage to the motor at three different frequencies at F, F/2, and F/3 where F is the fundamental frequency.

Dual Converter using Thyristors

This project defines a way to achieve bidirectional rotation of the DC motor by providing dc voltage at both polarities. Here a dual converter using thyristors is developed. The speed of the motor is also controlled by controlled the voltage applied to the thyristors using the firing angel delay method.
