Deals with switching issues in switch mode power supplies and high power converters and inverters. The switch mode power supply section investigates the operation and design of the standard switching power supply topologies such as the buck, boost, buck-boost, and Cuk switch mode converters. There is a brief introduction to resonant converter technology. The second section of the course considers high power converters and inverters. The terminal characteristics of the power devices used are investigated. Standard inverter topologies introduced, and various PWM algorithms for them are developed. Power quality issues and some solutions are presented. Multilevel converter topologies are introduced.
