Students will investigate the role of power electronics and power devices for global scale energy problems. The efficiency of converting and controlling electrical energy contributes significantly to making progress with green innovation. Power devices are key devices in the infrastructure of a society such as railroads, power transmission, renewable energy, automobiles, home electronics, and information devices. Compared to the human body, CPU and memory correspond to the brain, and power electronics to the heart. Students first learn about device physics which determine the performance of power devices from this course. They then gain an understanding of the structure and operating principle of various devices such as power diodes, thyristors, power MOSFET, and insulated gate bipolar transistors, as well as the characteristics of wide-gap semiconductor devices, in addition to learning the fundamentals for applying them to power electronics.
By the end of this course, students will be able to:
1) Express the physics and characteristics of semiconductor power devices
2) Explain the issues and key technologies for the power device applications and energy problem

At the beginning of each class, solutions to exercise problems that were assigned during the previous class are reviewed. Towards the end of class, students are given exercise problems related to the lecture given that day to solve. To prepare for class, students should read the course schedule section and check what topics will be covered. Required learning should be completed outside of the classroom for preparation and review purposes.

Students will be assessed on their understanding of the power devices (physics, device structure, characteristics, applications, and important roles in the society). Students' course scores are based on final exams (80%) and exercise problems during each class (20%).
No prerequisites are necessary, but enrollment in the related courses (Electron devices) is desirable.
