Modeling and Simulation of Averaged Switches

This course may also be credited toward ECEA 5705 in the CU Boulder Electrical Engineering Master of Science program. It is Course 1 in the Power Electronics Modeling and Control sequence. The course provides practical modeling and control of pulse-width modulated power converters using time- and frequency-domain analysis and simulation tools. A design-oriented analysis technique known as the Middlebrook Feedback Theorem is introduced and applied to the analysis and design of voltage regulators and other feedback circuits. Additionally, it is shown how circuit averaging and average switch modeling techniques result in average converter models suitable for manual analysis, computer analysis, and converter simulation. Upon completion of this course, the student will be able to practice designing high-performance switching power converter control loops using analytical and simulation techniques.

We strongly recommend that students complete the CU Boulder Power Electronics Specialization before enrolling in this course (course numbers listed are for CU Boulder MS-EE students): ● Introduction to Power Electronics (ECEA 5700) ● Converter Circuits (ECEA 5701) ● Converter Control (ECEA 5702) After completing this course, you will be able to: ● Explain the operation and modeling of switching power converters ● Model open-loop transfer functions and frequency responses ● Design closed-loop adjustable switching power converters ● Verify the operation of switching power converters through simulation ● Understand the principles of the feedback theorem ● Apply the feedback theorem to practical design examples ● Derive average switch models and average power converter circuit models ● Apply average switch modeling techniques to analysis, design and modeling of power converters
