Thyristor-controlled susceptance design based on reduced power switching compensator

In this study, a single phase thyristor-controlled susceptance (TCS) with integrated reduced power voltage source inverter (VSI) acting as a switching compensator (also known as active power filter) has been proposed to mitigate the harmonics generated by thyristor-controlled reactor (TCR). The proposed scheme has the capability to fully attenuate all harmonics generated by TCR. The proposed technique can perform efficiently even at lower switching frequency of VSIs, which is a desirable feature for higher power rating systems. This results in a more feasible implementation for comparative dynamic control characteristics. This scheme has been described in detail and has been verified through simulation and experimental results.
