Power electronics has found an important place in modern technology and has revolutionized control of power and energy. As the voltage, current ratings and switching characteristics of power semiconductor devices keep improving, the range of applications continues to expand in areas such as lamp controls, power supplies to motion control, factory automation, transportation, energy storage, multi- megawatt industrial drives, and electric power transmission and distribution. The greater efficiency and tighter control features of power electronics are becoming attractive for applications in motion control by replacing the earlier electro-mechanical and electronic systems.
Almost all new electrical or electromechanical equipment, from household air conditioners and computer power supplies to industrial motor controls, contain power electronic circuits. In order to keep up, working engineers involved in control and conversion of power and energy into applications ranging from several hundred voltages at a fraction of an ampere for display devices to about 10,000 V at high-voltage dc transmission should have a working knowledge of power electronics.
The design of power electronics equipment involves interactions with the source and the load, and utilizes small-signal electronic control circuits as well as power devices. Therefore power electronics draws upon, and indeed depends upon all of the other areas of electrical engineering.
Students conduct experiments on power electronics devices which include SCR, MOSFET, IGBT, and UJT. Students experience physically conducting multiple methods of turning on and off the power devices. Students study different circuits of power devices for rectification inversion and converting DC voltage to variable DC voltage. On completion of the lab students will be able to rotate motors using power devices, simulate experiments using P-SPICE simulator
