Course description and aims
This course presents analysis and control methods of power electronics circuits converting and controlling of electric power by using semiconductor switching power devices. It deals with switching transitions in MOSFETs and IGBTs, commutation in voltage-source bridge converters, voltage and current feedback control, applications to grid-connected converters, various grid-connection converters and related emerging technologies.
Analysis of power electronics circuit requires consideration of transient response in a very wide range of time scale from a utility grid period of 20 milli seconds to a switching transition of several hundred nano seconds. Although recent computers have a high calculation performance, a lot of computation would be required to analyze the dynamic response in a long duration with a quire small time step. This course introduces some analysis and modeling methods to solve the dynamic response of the power electronics converters effectively. These methods are also valuable for controlling these converters. Student are expected to study these fundamental methods as well as their applications to various other practical problems.
Student learning outcomes
By the end of the course, students will be able to:
1) Understand the basic structure and driving methods for power MOSFETs and insulated gate bipolar transistors (IGBTs).
2) Understand the circuit topology and operating principles in basic power electronics circuits.
3) Analyze the operating characteristics of basic power electronics circuits.
Keywords
