Entry requirements
120 credits in science/engineering, including basic knowledge in electric circuit theory, electronics and power engineering. Participation in Transform Methods (spec. Fourier series), or the course can be taken in parallel. 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:
- explain the static and dynamic characteristics of fundamental power semiconductor devices.
- apply the principles of AC/DC and DC/DC converters, and calculate performance parameters from averages, RMS values and peak values of the related circuit parameters,
- calculate and evaluate harmonics at rectification and inversion,
- apply the control of power converters using pulse-width modulation (PWM) .
- apply the basic working principle of switch-mode inverters,
- simulate power electronic circuits,
- conduct experiments with converters and compare the results with theoretical concepts or simulations,
- design and analyse various types of converters.
Content
Overview of power semiconductor devices: Diodes, Thyristors, transistors such as BJT, MOSFET, IGBT. Rectifiers: Single-phase and three-phase diode rectifiers with different types of loads, Average power output, Performance parameters, Harmonic analysis. Switch-mode DC-DC converters: Design, analysis and control of Step-down (Buck), Step-Up (Boost), Buck-Boost and Full-bridge topologies, Pulse-width modulation (PWM) scheme, characteristics of controllable switches, continuous and discontinuous current mode. Switch-mode DC-AC converters: Basic inverter concept, Sinusoidal PWM.
Instruction
Lectures and tutorials, laboratory work including simulation exercises.
Assessment
Written exam (3 credits), 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.
Other directives
Cannot be included in the same degree as 1TE300 Power Electronics.
