Course ContentIntroduction Features of Power Processing Systems: Ideal DC and AC waveforms; DC figures of merit – ripple factor and average value; AC figures of merit – harmonic factor, distortion factor, THD, power factor, crest factor. Semiconductor Devices: SCR – static v-i characteristics, dynamic characteristics, commutation, turn-on methods; Power Diode; Power MOSFET; IGBT. Simple Power Electronic Circuits: SCR circuits with R load, RL load, RL load and freewheeling diode – continuous and discontinuous modes of operation. Rectifiers: Single phase diode bridge – R load, constant dc-side current, effect of source inductance, constant dc-side voltage; Three phase diode full-bridge with constant dc-side current – ideal circuit, effect of source inductance; Single phase full-controlled thyristor bridge – constant dc-side current, effect of source inductance, inverter mode of operation; Three phase full-controlled thyristor bridge – constant dc-side current, effect of source inductance; Higher pulse rectifiers. Converters: Basic non-isolated topologies: Buck, boost, buck-boost and cuk converters – steady state analysis under continuous and discontinuous modes of operation; Steady state analysis of a few isolated topologies. Inverters: Pulse-width-modulated inverters – sine-triangle modulation, single phase half-bridge inverter, single phase full-bridge inverter – unipolar and bipolar schemes, three phase inverters; Square wave inverters – single phase and three phase (180 degree mode of operation); Effect of blanking time; Other inverter control techniques – single phase output control by voltage cancellation, Selective Harmonic Elimination (SHE), hysteresis control; AC Voltage Controllers: Configuration and basic operation, application.
