Course description and aims

This course covers an outline of the history, the theory, current problems of power devices. The power device, which treats high withstand voltage and a destruction limit of several hundreds V ~ several thousands V, works by the mechanism that is unexpectedly simpler than memory and a CPU. We introduce a basic, simple way of thinking necessary for the understanding. In this lecture, We would show the discovery of the problem in the power device development, an example of the solution.

Student learning outcomes

1. Grasping basic information to use power devices.
2. Understanding the principle of the power device key operation.
3. Knowing a portion of the development activity in the industry.


pin diode, IGBT, destruction phenomena and their limit (Safe Operating Area), SiC and GaN devices.
