Power electronics is a subject that concerns the application of electronic-principles into situations that are rated at power level rather than signal level. It may also be defined as a subject that deals with the apparatus and equipment working on the principle of electronics but rated at power level rather than signal level.
Advantages of power electronics are as follows –
(i) High reliability of power-electronic converter systems.
(ii) High efficiency due to low loss in power-semiconductor devices.
(iii) Fast dynamic respones of the power-electronic systems as compared to electromechanical converter systems.
(iv) Small size and less weight result in less floor space and therefore lower installation cost.
