Course overview
This course will train students in designing power converters through modelling, simulation and controller synthesis using industry-standard tools. Principles of power electronics. Characteristics (including datasheet parameters) of power semiconductor devices, e.g., power diode, power MOSFET, IGBT, thyristors, wide-bandgap semiconductor devices. Simulations using SPICE and MATLAB/Simulink. Figures of merit (e.g., efficiency, power factor, ripple, total harmonic distortion) and power-related computations. Continuous current mode vs. discontinuous current mode. DC-DC conversion, including buck, boost, buck-boost and Cuk. Modelling (large-signal vs. small-signal, state-space vs. frequency-domain), system identification, and design of controllers for DC-DC converters. AC-DC conversion (rectification): half-wave vs. full-wave, uncontrolled vs. controlled, single-phase vs. three-phase. DC-AC conversion (inversion): voltage-source vs. current-source, single-phase vs. three-phase. Applications of power converters, including case studies of latest trends.
