The purpose of the course is to provide knowledge about dimensioning and use of modern semiconductor components and related passive components in their applications in power electronic converters. The learning includes mechanical, electrical and thermal dimensioning of semiconductor components as well as inductors and capacitors, including modeling of their service life given a certain thermal and electrical cycling. Furthermore, the course provides knowledge of principles for modulation, current and voltage control for different converter types. The course provides an understanding of applications of power electronic converters such as switched power supplies, motor drive systems, solar cell converters, electric vehicle chargers etc. Furthermore, power grid applications such as "Unified Power Flow Controllers" (UPFC), active power filters, high voltage direct current (HVDC) etc. are studied. Learning consists of lectures, arithmetic exercises, simulation work and lab work where simulations and laboratory work are closely linked.

Lectures and arithmetic exercises Components: Diodes, transistors (BJT, IGBT, MOSFET), materials (silicon, silicon carbide), inductors, capacitors, sensors (current, voltage). Function, mechanical and thermal design, aging. Circuits: Drive and protection circuits. Various bridges such as 1Q, 2Q and 3-phase 2- and multi-level converters. Parasitic components, load currents and earth currents. Modulation and control: Carrier modulation, sampled current control, tolerance band control of current, voltage control. Applications: Switching power supplies, motor drive systems for DC and AC motors, solar cell converters, electric vehicle chargers, "Unified Power Flow Controllers" (UPFC), active power filters, high voltage direct current (HVDC). Simulation tasks and laboratory work Primary switched power supplies. 4-quadrant converter. Modulation with fixed and random frequency. Feedback current control. 3-phase voltage generation for 230 V 3-phase. These labs are prepared through simulation work, which is reported as a homework before the lab. After the laboratory, a report is written where simulations and measurements are compared.
