Abstract
This article presents a comparative study through analyses regarding a number of power electronics devices. Power Electronic devices have innovative contribution to control the electrical power operations with a degree of precision. The GTO normally are not equipped with amplifying gates. The Asymmetric GTOs are inherently equipped with fast recovery diodes across each GTO, for reverse operations based on the that reverse voltage capability is not required for GTOs operations. This also provide techno economic benefits high voltage, voltage drop and current ratings capability. It can sustain against, short and long-time overcurrent.
