Abstract

This paper discusses the different types of power semiconductor devices. It also describes the operation, characteristics and applications of different devices. The principle of operation and the key features of different devices is discussed. The other thyristor group devices, such as Triac having capability to conduct in both positive and negative half of ac supply and GTO with facility to turn-on and turn-off from the gate were made commercially available in 1960s. The power Static Induction Transistor (SIT) in modern form was commercially introduced by Tokin Corporation of Japan in 1987. Its conduction drop is very large but switching frequency is very high. A Static Induction Thyristor (SITH) is a self controlled GTO.General Electric announced a MOS-Controlled Thyristor (MCT)which is a high power, high frequency GTO like device with MOS-gated turn-on and turn-off characteristics.
