To develop an ability to analyse and design power electronic circuits and schemes of energy systems.

Content Summary

Power Electronic Devices - Operating and control characteristics of devices (power diodes, power transistors, thyristors, triac).

Power Electronic Converters - Analysis of single-phase and three-phase uncontrolled and controlled rectifiers, single-phase and three-phase inverters, ac-ac single-phase and three-phase converters, dc choppers (for motors) and fundamental dc-dc switch mode converters. Analysis of multi-level converters: Cascaded H-Bridges, Diode-Clamped and Flying-Capacitor. Modulation techniques for converters. Design of converter circuits.

Electric/Hybrid Vehicles - Theory for three-phase induction motors, dc motors and synchronous motors (especially permanent magnet ac and switched reluctance types). Analysis of power electronic converter variable speed drive schemes for a range of motors and converters, including speed and torque control methods. Regenerative braking with power electronic converters.

Solar PV Systems - Grid connected: analysis of single-phase (with and without dc-dc conversion stage) and three-phase inverter schemes. Stand alone: schemes with dc-dc converters and with inverters; power electronics for solar water pumping schemes. Design of photovoltaic systems.

FACTS Devices - Operation of devices (TCR, TSC, SVC, TSSC, TCSC, TCPAR and STATCOM) in controlling power flow in ac transmission systems.

Wind Turbines (grid connected) - Fixed speed: analysis of soft starters and power electronic reactive power compensation techniques for fixed speed schemes (cage induction generator). Variable speed: analysis of the back-to-back voltage source converter scheme for the doubly-fed induction generator (DFIG); analysis of the fully-rated back-to-back voltage source converter scheme for the cage induction generator and for the synchronous generator.

High Voltage Power Transmission - Analysis and design of three-phase bridge line-commutated converter (LCC) and three-phase bridge voltage source converter (VSC) HVDC link schemes for offshore windfarms. The VSC (inverting mode) and high voltage power transmission with solar photovoltaic source.

Grid Interfacing - Power electronic interfacing of renewable energy power systems with the grid (control of voltage, frequency and power).

Electrochemical Devices - Fuel-cell power electronics for distributed generation. Power electronic battery cell voltage equalizers.
