Abstract

The purpose of this project is to design thyristor circuits by using single-phase FCRO 4100 firing board donated by ENERPRO. These circuits in conjunction with a thyristor module will be used for future lab experiments in power electronics courses.

The first part of this project is to study the full effect of a firing angle on a controlled single phase full bridge thyristor rectifier circuit. Furthermore, the resulting circuit setup will be implemented as part of future lab experiments in Power Electronics I course. The next purpose of this project is to design a small-scale Static VAR Compensator (SVC) lab experiment for use in Power Electronics II course. The lab experiment will show how to correct power factor using thyristors in a phase-controlled circuit. A resistor and an inductor will be used to mimic a customer inductive load. A thyristor controlled reactor (TCR) in parallel with a capacitor will be the SVC. By adjusting the firing angle α of the TCR, reactive power can be either injected or absorbed into the system to achieve a higher power factor and ultimately a more efficient power system.
