Subject aims expressed by acquired skills and competences

The course aims to provide students with knowledge to enable good orientation on the principles of power semiconductor systems both in automotive technology and applications that relate to the use of automobiles. Student gains the ability of independent analysis and synthesis of power semiconductor components and systems able to apply their knowledge in practical design of power semiconductor converters.

Teaching methods

Experimental work in labs


Power electronics is a branch which intensively enters all technical areas of the present living. Practical utilization of the conversion principle of the electric energy via semiconductor switching devices requires apart from the knowledge about principle and function of elementary semiconductor converters also especially about their industrial and commercial applications. The subject provides pieces of knowledge to students in field of automotive power electronics.
