6.622 Power Electronics (Spring 2023, MIT OCW). Instructor: Prof. David Perreault. 6.622 covers modeling, analysis, design, control, and application of circuits for energy conversion and control. As described by the Institute of Electrical and Electronics Engineers (IEEE), power electronics technology "encompasses the use of electronic components, the application of circuit theory and design techniques, and the development of analytical tools toward efficient electronic conversion, control, and conditioning of electric power." Students taking this class will come away with an understanding of the fundamental principles of power electronics, and knowledge of how to both analyze and design power electronic components and systems.

Lecture 15 - Switching Losses and Snubbers
In this lecture, we do a back-of-the-envelope calculation on semiconductor losses, including conduction losses and switching losses. We also explore the use of snubbers to modify the switching transitions to reduce noise, protect the semiconductor devices, and reduce internal device dissipation.
