The course introduces into the problematic of power electronics. First part of lectures deals with principles and structures of contemporary semiconductor power devices. The impact of novel semiconductor materials is discussed, as well. Circuit models of particular devices will be then explained, driving circuits, switching of the resistive, inductive and capacitive loads, power losses and device operation reliability will be thoroughly discussed. Second part of lectures is dedicated to the problematic of power converters, their topologies, control techniques and circuits. Electromagnetic compatibility and PCB design for power converters will be discussed, as well.
