Module Overview
This module aims to develop a better understanding of power semiconductor switching devices and various power converters. A detailed analysis of power converters like AC to DC phase controlled rectifiers, AC to AC, DC to DC converter & Pulse Width Modulated (PWM) inverters will be provided. In order to develop a broader understanding of this subject, a few domestic & industrial applications will be taught in this module.
