• To develop an ability to analyse motor drive schemes and apply control techniques.

• To provide a detailed understanding and ability to evaluate switch mode techniques and system.

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, cyclo converters 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

• Analysis of ideal buck, boost, buck-boost and cuk converter circuits. Analysis of ideal flyback and forward converters. Effects of parasitics on converter operation. Synchronous and bidirectional converters. Voltage-mode and current-mode PWM control methods.
• Principles of soft-switching techniques and analysis of common soft-switching converter topologies.
• Magnetic design theory for transformers and dc inductors.
• Design of switch mode circuits and systems.
