MCQs on Power Electronics-Part-1
With the advent of semiconductor devices, revolution is taking place in the power transmission distribution and utilization. This course introduces the basic concepts of power semiconductor devices, converters and choppers and their analysis. Phase control technique — Single phase Line commutated converters — Mid point and Bridge connections — Half controlled converters with Resistive, RL loads and RLE load— Derivation of average load voltage and current — Active and Reactive power inputs to the converters without and with Free wheeling Diode —Numerical problems.
