POWER ELECTRONICS

Scope of the module is to introduce students into the theory and applications of Power Electronic Systems. All main types of Power Electronics converters are studied, employing various teaching methods. The students are required to implement a selection of laboratory experiments that cover all the main types of converters, providing relative laboratory reports. Furthermore, students are required to complete various assignments, dealing with simulating of power electronic circuits using specialized software, solving of problems and practical applications. Special emphasis is given to electronic constructions of converters through a relevant construction project that students must implement.

Objectives
