Explore the fundamentals of inverters in this 51-minute lecture from MIT's Power Electronics course. Begin with a comprehensive review of Fourier Series and waveform characteristics in both time and frequency domains. Delve into the decomposition of waveforms into odd and even components, as well as half-wave symmetric and half-wave repeating components. Gain an introduction to the single-phase full-bridge inverter, also known as a dc-to-ac converter, and learn simple techniques for controlling its AC output. Part of MIT OpenCourseWare's Spring 2023 offering, this lecture is instructed by David Perreault and is available under a Creative Commons BY-NC-SA license.
