Course Objectives: Electrical power is widely used in every part of home and industry from milliwatts to megawatts. The main objective of power electronics is to improve the quality and utilization of electrical power. Efficient use of power will, therefore, conserve the energy resources of the world. Power electronics addresses the conversion techniques of electrical energy to achieve these goals.
