Design Motor Controllers with Simscape Electrical, Part 5: Alternative Implementation of PWM Control

This video demonstrates how you can modulate the three-phase voltages directly using PWM control. The commutation logic is modeled such that the commutating phases switch between a positive and negative DC source voltage in a complementary fashion. This way the three-phase voltages seen by the motor are being averaged. The back-EMF voltages in the non-commutating phase help us estimate the approximate value of the averaged phase voltage.
