Content Summary
Power Electronic Devices
Operating principles and control characteristics of devices (power diodes, power transistors, thyristors, triac).
Power Electronic Converters
Conversion processes of single-phase and three-phase rectifiers (uncontrolled and controlled), inverters, cycloconverters and ac voltage controllers. DC choppers (for motors).
Calculation of peak, mean and rms values of current and voltage for converters. Calculation of harmonics and harmonic distortion factors. Conversion efficiency and power factor calculations.
Design of snubber circuits for limitation of dv/dt and di/dt.
Multi-level converters - Cascaded H-Bridges, Diode-Clamped and Flying-Capacitor converters.
Modulation techniques for converters.
Electrical Machines and Drives
Analysis of dc motors, three-phase induction motors and synchronous motors (especially permanent magnet ac and switched reluctance types).
Analysis of motor drive schemes for a broad range of motors and power electronic converters. Analysis of speed and torque control techniques, including vector control.
Switch Mode DC-DC Power Supplies
