The project is designed to control AC power to a load by using firing angle control of thyristor. Efficiency of such power control is very high compared to any other method.

The project uses zero crossing point of the waveform which is detected by a comparator whose output is then fed to the microcontroller. The microcontroller provides required delayed triggering control to a pair of SCRs through opto isolator interface.

Finally the power is applied to the load through the SCRs in series. This project uses a microcontroller from 8051 family ....etc

integrated gate commutated thyristor igct ppt

The integrated gate-commutated thyristor (IGCT) is a power semiconductor electronic device, used for switching electric current in industrial equipment. It is related to the gate turn-off (GTO) thyristor. It was jointly developed by Mitsubishi and ABB.Like the GTO thyristor, the IGCT is a fully controllable power switch, meaning that it can be turned both on and off by its control terminal (the gate). Gate drive electronics are integrated with the thyristor device.

All ABB IGCTs (Integrated Gate-C ....etc

ppt on a combination of shunt hybrid power filter and thyristor controlled reactor for power quality

This paper proposes a combined system of a thyristor-controlled reactor (TCR) and a shunt hybrid power filter (SHPF) for harmonic and reactive power compensation. The SHPF is the combination of a small-rating active power filter (APF) and a fifth-harmonic-tuned LC passive filter. The tuned passive filter and the TCR form a shunt passive filter (SPF) to compensate reactive power. The small-rating APF is used to improve the filtering characterist ....etc

speed control of dc motor using thyristor dual converter with pid controller

ABSTRACT

The paper describes the design, construction and testing of a closed-loop system for the speed control of a separately excited d.c. motor fed from a dual converter. The dual converter makes possible regenerative braking and reversal of direction of rotation. There is only one firing unit and the firing pulses are diverted to the appropriate converter by a master controller. There are three control loops: one for armature current control, one for adjusting th ....etc

INTRODUCTION

Boost converter is one of the most popular choices for high-quality rectification. The converter is supplied from a full-wave rectified line voltage and operated so that the input current follows the input voltage. The input current shaping can be achieved using a number of techniques. When the converter is operated at fixed frequency and fixed duty ratio in the discontinuous conduction mode (DCM), the low- frequency component of the input current is approximately proportional to the input ....etc
