What is a PWM inverter?
What is a PWM Inverter and How PWM Inverters Work? A PWM (Pulse Width Modulation) Inverter is a device that converts direct current (DC) to alternating current (AC) by modulating the width of the pulses in the output signal. It generates a series of pulses with varying widths to create an AC waveform that closely approximates a sine wave.
