PWM (Pulse Width Modulation) inverters are power electronic devices that convert DC to AC power using pulse width modulation techniques. The technology of PWM plays a pivotal role in enhancing efficiency, minimizing harmonics, and improving voltage regulation in inverters. Inverters do the opposite of rectifiers which were originally large. . An inverter controls the frequency of power supplied to an AC motor to control the rotation speed of the motor. The voltage at the input terminals is constant. controlled turn-on and turn-off. bridge or full-bridge configuration.
