Power Electronics deals with study of semiconductor devices in the electric energy industry. The power semiconductor devices, such as the diode, thyristor, triac and power transistor, are used in power applications as switching devices. The modern electrical engineer requires a knowledge of these devices and their application in rectification, inversion, frequency conversion, dc and ac machine control, and controlled power supplies. Engineers need to be aware of the undesirable effects any power electronics equipment imposes on both the supply system and the load, and how these effects may be minimised.
