ELEN7056 Power Electronics

School running course: 
Electrical & Information Engineering
Year of Study: 
  • This unit introduces students to the application of the two most important semiconductor devices for the control of power – the silicon controlled rectifier (SCR) and the insulated gate bipolar transistor (IGBT). The unit then proceeds to examine the circuits, and analyse the performance of the various types of variable speed drives for both AC motors (synchronous and induction) and DC motors.
  • The problems associated with variable speed drives, such as the injection of current harmonics back into the supply are also examined. Characteristics, ratings and protection of SCR’s, GTO’s, BJT’s, MOSFET’s and IGBT’s.
