In today s energy conservative world, an efficient means of processing and controlling energy from one form to another to satisfy different load requirements is crucial and needed. The technology that deals with this issue is called Power Electronics. Power Electronics is one of the broadest growth areas in electrical technology. Today, electronic energy processing circuits are needed for every computer system, every digital product, industrial systems of all types, automobiles, home appliances, lamps and lighting equipment, motor controllers, and just about every possible application of electricity.
Today there are many more benefits in terms of reliable, lightweight power processors.
A host of new applications is made possible by improvements in semiconductors and by better understanding of power electronics. Motors with integrated electronic controls will soon be the norm. Portable telephones and communication device demand tightly optimized power management. Advanced microprocessors need special techniques to supply their power. Utility companies worry about the quality of their product, and about how to use electronics for more effective power delivery.
