Language of instruction: The course will be given in English on demand
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.

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
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.
Grading scale: TH - (U,3,4,5) - (Fail, Three, Four, Five)
Assessment: Approved laborations and simulations that are reported continuously. Written exam (5 h) with both problem solving and theoretical questions.
The examiner, in consultation with Disability Support Services, may deviate from the regular form of examination in order to provide a permanently disabled student with a form of examination equivalent to that of a student without a disability.
