Aim: The course objective is
- to provide the student with a basic knowledge of how to design switch mode DC - to - DC 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 convertertopology to any given application. |
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. Synchroniuous rectifiers. Power factor controllers. Switched amplifiers.
