Syllabus
Course overview and goals
In various situations of electricity generation, power transmission, distribution, and power use, by converting voltage, current, and frequency to match the equipment, an efficient use in electric power becomes possible. The key device for highly efficient conversion is the power device. This course provides the basics of physics, device structures, device characteristics of the power devices, and their applications. Topics include pin-diodes, thyristors, power MOS transistors, Insulated Gate Bipolar Transistor (IGBT), and wide-gap semiconductor power devices.
Course description and aims
The goals of this course are as follows.
1) Explain the physics and characteristics of semiconductor power devices
2) Explain the characteristics of wide-gap semiconductor devices
Keywords
Power devices, Power Converters, Wide-gap semiconductors
Competencies

- Intercultural skills
- Communication skills
- Critical thinking skills
- Practical and/or problem-solving skills
- ・Applied specialist skills on EEE
Class flow
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.
