| Summary |
|---|
| 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 applied and commercial electronics, power electronics, electric drives and other segments of electrical engineering. |
