3 phase inverter basics

The video tutorial explains the process of converting a rectified 3-phase AC supply into a ripple DC waveform using diodes and capacitors. It then details how to use a three-phase inverter with IGBTs to convert the DC into a three-phase AC supply. The tutorial covers the switching sequence required to simulate the three phases and discusses the use of pulse width modulation to refine the AC output. The video concludes with a summary of the process and thanks the viewers.

How does the oscilloscope help in verifying the output waveform of the AC supply?

What is pulse width modulation and how is it used in generating three phase AC supply?
