University of Colorado, Boulder has partnered with Coursera to offer this free course starting September 1.

The course is an introduction to switched-mode power converters. It provides a basic knowledge of circuitry for the control and conversion of electrical power with high efficiency.

The course is an introduction to switched-mode power converters. It provides a basic knowledge of circuitry for the control and conversion of electrical power with high efficiency. These converters can change and regulate the voltage, current, or power; dc-dc converters, ac-dc rectifiers, dc-ac inverters, and ac-ac cycloconverters are in common use. Applications include electronic power supplies, aerospace and vehicular power systems, and renewable energy systems.

- Introduction to power electronics

I. Converters in Equilibrium

- Principles of steady-state converter analysis
- Steady-state equivalent circuit modeling, losses, and efficiency
- Semiconductor power switch realization
- The discontinuous conduction mode
- Converter circuits and transformer isolation

II. Converter Dynamics and Control

- AC equivalent circuit modeling
- Converter transfer functions
- Controller design

Knowledge of circuits and electronics at the level of an undergraduate major in electrical engineering is assumed.

The lectures are designed to be self-contained. The following textbook was developed for use in this class; it is recommended but not required:

The class will consist of lecture videos that are 5 to 25 minutes in length. These will contain integrated quiz questions. In addition, the course will require standalone homework each week that is machine graded.

**Will I get a Statement of Accomplishment after completing this class?**Yes. Students who successfully complete the class will receive a Statement of Accomplishment signed by the instructor.**What resources will I need for this class?**For this course, all you need is an Internet connection, and the time to watch, study, and learn the field of power electronics. You may also choose to obtain a copy of the optional textbook.**What is the coolest thing I’ll learn if I take this class?**You will learn how control substantial electrical power with very high efficiency using time-varying switching converters.
