Aim: The course objective is
- to provide the student with a basic knowledge of how to design switch mode converters.
- to enable the student to analyse and understand the operation of an unknown converter topology.
- to enable the student to perform a rational choise of converter topology to any given application.
- to provide the student with an overview of applications for power semiconductors and circuits
- to enable the student to evaluate power electronic circuits and components good and bad characteristics. |
| Contents: Buck, Boost and Buck-Boost converters. Steady state transfer functions. Voltages and currents in the circuit. Continuous - and discontinuous conduction mode. Isolated convertertopologies (Fly-back, Forward, UK, Push-pull, Half-bridge, HY-bridge, Weinberg etc.). Control and protection circuits (Error-amplifiers, Auxiliary supply, undervoltage - and overvoltage protection, current limit etc.). Input- and output filters. Inductors and transformers. Selection of power-semiconductors and passive components. Snubber circuits. Driver circuits. Voltage- and current-mode regulation. An overview of synchroniuous rectifiers, power factor controllers and switch mode (class D) amplifiers. |
