Course Description

Power Electronics is a filed of power conversion and system control through applications of power semiconductor devices. In class, fundamental lectures include the basic of poser conversion by switching circuit and circuit behavior in transient. The applications include the control methods of power sources and motors by conversion circuits.


The final evaluation is decided based on examination (70%) and homework (30%).

Course Goals

Students are expected to learn the method of power conversion and its applications based on circuit theory, switching circuit, and semiconductor engineering. They are also requested to understand the method for achieving the functions of actuators through the control of electric power convertor.
