Entry requirements

130 credits in science/engineering including 10 credits at Master's level. Attended Power Electronics I. Proficiency in English equivalent to the Swedish upper secondary course English 6.

Learning outcomes

On completion of the course, the student should be able to:

• analyse and design isolated DC-DC converters and account for their control,
• analyse and design switch mode DC-AC voltage converter,
• analyse harmonics for different pulse width modulation (PWM) switching techniques,
• account for different topologies of multistage converters,
• analyse resonant converters,
• estimate losses in power electronic components and dimension heat sinks.

Content

DC-DC converters: Flyback-, Forward and Full-bridge converter topologies, functional principles, waveform analysis, simulation studies, control. DC-AC converters: introduction of various converters, voltage source inverters (VSI) and current source inverters (CSI), half- and full-bridge VSI topologies, unipolar and bipolar PWM schemes, harmonic analysis of different PWM switching techniques. Multilevel inverters: application areas, topologies, characteristics of various types, diode-clamped type and cascade-type, principles and applications. Resonant converters: topologies, characteristics of zero-voltage and zero-current switching. Thermal management: losses in components and dimensioning of heat sinks.

Instruction

Lectures, tutorials, computer simulations and laboratory exercises.

Assessment

Written examination (3 credits) as well as presentation of laboratory exercises (2 credits).

If there are special reasons for doing so, an examiner may make an exception from the method of assessment indicated and allow a student to be assessed by another method. An example of special reasons might be a certificate regarding special pedagogical support from the disability coordinator of the university.
