Learning outcomes
After a successfully completed course the student should be able to:
- explain the static and dynamic characteristics of fundamental power semiconductor devices.
- explain the working principle of uncontrolled rectifiers and calculate the performance parameters from the average, RMS and peak values of the related circuit parameters.
- calculate harmonics in the output and input currents for rectifier operations.
- design and analyse various types of switch-mode DC converters.
- explain the control of power converters using pulse-width modulation (PWM) .
- describe the basic working principle of switch-mode inverters,
- simulate simple power electronic circuits using simulation packages like Spice or MATLAB/Simulink.
- conduct experiments with converters and compare the results with theoretical concepts and simulations..
