Pulse Width Modulated (PWM) Drives
Essentially, these techniques require switching the inverter power devices (transistors or IGBTs) on and off many times in order to generate the proper RMS voltage levels.
Sinusoidal Pulse Width Modulation
The carrier-based PWM technique fulfills such a requirement as it defines the on and off states of the switches of the inverter legs by comparing a modulating signal vc (desired ac output voltage) and a
