What is Power Electronics?

For descriptive purposes, it is frequently useful to divide the overall field of electrical engineering into three areas of specialization: electronics, power, and control. The electronics area deals primarily with devices and circuits for the processing of information; the power area deals with both rotating and static equipment for the generation, transmission, distribution, and utilization of vast quantities of electrical power; and the control area deals with the stability and response characteristics of closed-loop systems using feedback on either a continuous or sampled-data basis.INTRODUCTION TO POWER ELECTRONICS
Interstitial to all three of these areas is power electronics, which deals with the use of electronics for the control and conversion of large amounts of electrical power.
“The task of power electronics (circuits/systems) is to process and control the flow of electric energy or power by supplying voltages and currents in a form that is optimally suited to the load.”
POWER ELECTRONICS (Introduction) Power Input:
  1. From electric utility: ac input, 1 or 3 phase, 50 or 60 Hz
  2. From dc supply/battery: dc input
  3. From previous converter output: ac/dc input
Power Converter Core : Using BJT/ MOSFET/ SCR/ GTO/ IGBT/ MCT as switch, Diode, L and C as energy manipulators
Power Output: to load (load can be of R or L or R-L nature) output parameters: dc/ac voltage, dc/ac current, frequency & number of phase
Power Converter
