ABSTRACT

Controlled AC/DC converters are usually called controlled rectifiers. They convert an AC power supply source voltage to a controlled DC load voltage. Controlled AC/DC conversion technology is a vast subject area spanning research investigation to industrial applications. Usually, such rectifier devices are thyristors (or SCRs—silicon-controlled rectifiers), gate-turn-off thyristors (GTOs), power transistors (PTs), insulated gate bipolar transistors (IGBTs), and so on.
