About the Course

This course can also be taken for academic credit as ECEA 5701, part of CU Boulder’s Master of Science in Electrical Engineering degree. This course introduces more advanced concepts of switched-mode converter circuits. Realization of the power semiconductors in inverters or in converters having bidirectional power flow is explained. Power diodes, power MOSFETs, and IGBTs are explained, along with the origins of their switching times. Equivalent circuit models are refined to include the effects of switching loss. The discontinuous conduction mode is described and analyzed. A number of well-known converter circuit topologies are explored, including those with transformer isolation. The homework assignments include a boost converter and an H-bridge inverter used in a grid-interfaced solar inverter system, as well as transformer-isolated forward and flyback converters. After completing this course, you will: ● Understand how to implement the power semiconductor devices in a switching converter ● Understand the origins of the discontinuous conduction mode and be able to solve converters operating in DCM ● Understand the basic dc-dc converter and dc-ac inverter circuits ● Understand how to implement transformer isolation in a dc-dc converter, including the popular forward and flyback converter topologies Completion of the first course Introduction to Power Electronics is the assumed prerequisite for this course....

A really good course on converter circuits. The way Dr. Erickson synthesized inverters from buck converters was eye opening. Many lectures overlook such basic aspects of power electronics synthesis.

Great follow on to the Introduction to Power Electronics. Provides a great logical deepening of understanding and practical impacts that can help to understand real-world behaviour and problems.

Frustrated throughout the course with the homework system. Please implement a system that provides helpful feedback and more worked out examples.

This course is very difficult, particularly in week 4. The single sample problem with solution provided is utterly useless in helping you prepare for the assessment. It does not parallel the material covered in the lessons and does not prepare you for the assessment. It's bizarre to me that there aren't at least 5 practice problems with solutions that help you prepare for the assessment. Having this is critical to taking an online class by yourself, since the forum cannot be relied upon for timely help, if at all.

some of the equations which needs to be answered in Homework is very complex, almost impossible to find the mistakes, even if one is right on the track.

The course is awfull. Yes. It gives a lot of directions for further self-work and forces the learner to be effecient in finding the right materials. But the course is also expected to be something pleasant and interesting to follow. But here first you watch really dull videos for a couple of hours and then you are faced agains really hard homeworks without no support whatsoever. Does not build up motivation to continue at all.

Videos are useless as far as completing the assignments is concerned. Either the videos are ridiculously lacking, or the assignements are way off course.

Extremely poor homework assignments. In most instances, the homework problems do NOT enforce the material of the week!

Where is the course certificate?
