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.

This course is offered every fall semester. It will next be offered in Fall 2018. Instructor: Prof. Bob Erickson. It is the first of the three courses required for the Professional Certificate in Power Electronics. In addition, this course provides the theoretical basis for the Power Electronics and Photovoltaic Power Systems Laboratory course, ECEN 4517/5517.

The required prerequisite for the course is ECEN 3250 Microelectronics or equivalent. It will be assumed that all students have completed a 1.5-2 year sequence of undergraduate circuits and electronics courses for EE majors.

The course is offered both to regular on-campus students and also to off-campus distance students Further details of the course policies, including procedures for off-campus students, are listed on the Vitals page.
