Course description and aims

From the trend of energy conversion to electric power and demands of the energy saving, the expectation to high efficiency electricity conversion technology continues increasing. We introduce history, basic theory, current status, and problems focusing on power devices which play the key role in this electronic power conversion technology. Though power devices treat from several tenths of volts to several thousands of volts for each application, basic technology and operation are comparatively common. We aim to explain this common technology for understanding the detailed and latest power conversion technologies.

Student learning outcomes

1. Grasping basic information to use power devices.
2. Understanding the principle of the power device key operation.

Assessment criteria and methods

Grading evaluation will be made from the midterm and final reports. The midterm report is to evaluate the fundamental understanding of power devices. The final report is to confirm the overall understanding of operating principles and industrial applications of power devices presented through this course. Moreover, the process of the derivation will be evaluated as well as the correctness of the answer.
