introduction: Thyristor is a general term and it consists of a family of power semiconductor devices such as SCR, light activated SCR (LASCR), GTO, TRIAC, etc. These devices are used extensively in power electronics circuits. These devices operate in conducting and non-conducting states. The conduction of thyristor is possible by providing current to gate terminal. …
introduction: Phase Controlled Rectifier These convert constant AC voltage to variable DC output voltage . These rectifiers use line voltage for their commutation. These are also called line commutated or natural commutated AC-to-DC converters. It is may be fed from a single phase or three-phase source. It is mainly used in DC drives, metallurgical and …
