课程内容简介(Course Introduction):

The modeling and control of power electronic system is a basic course and important skill for the graduate students, especially in the field of Power Electronics and Motor Drive. In order to achieve satisfactory output performances/accuracies in various power conversion applications (both in dynamic and static), power electronic converters nowadays demand not only carefully-designed circuits, but also a reliable closed-loop control system. However, being as the control plant, the power electronic converters normally have strong non-linearity and complex circuit topologies, which result in challenges for correct extraction of mathematical models as well as the design of the control loop. The goal of this course is to clarify the commonly-used modeling ideas/theories in the field of power electronics; to introduce the control methods and modelling process for typical power electronic circuits; and to train the capability of analyzing and designing the control system for power electronics circuits.

This course starts with the basic DC-DC converter as an example, the operating modes, modeling methods, control methods as well as the design/realization of the control loop are first introduced. Afterwards, the course will put focus on the single phase and three-phase DC-AC converters, the coordinate transformation theory, modulation method, and the design of voltage/current feedback control loops, will be specified. Finally, some advanced control technologies such as LCL filter design/control, virtual impedance control and grid synchronization will be given.

 

 

教学大纲(Course Teaching Outline):

This course will be arranged in the following 6 chapters, including some hours for practices in design and simulation. In addition to the content of the course, some simulation models and practices will be included under the PLECS simulation platform, in order to help students to better understand the key points of knowledge.

1. Basic of Converter Modeling: state average concept; large/small signal modeling; DCM/CCM operation modes; models for normally used DC-DC converter topologies

2. Basic of Converter Control: overview of converter control; Controller and control targets; current peak control for DC-DC converter and improvement; voltage control and feedback loop design for DC-DC converter

3. DC-AC Converter Modeling: applications of DC-AC converter; single-phase inverter modeling; coordinate transformation theory; three-phase converter modeling

4. DC-AC Converter Control: DC-AC converter control overview; PWM modulation technology and modeling; current control and feedback loop design; voltage control and feedback loop design
