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.
The Pulse Width Modulated (PWM) inverter offers the ability to change both the magnitude of the voltage and the frequency using a fixed DC voltage as the input. This means a diode rectifier can be used as the front end of the drive, which appears as a constant power factor load to the source.
This paper presents a comprehensive overview of PWM techniques for two-level voltage source inverters and provides a comparative analysis of commonly employed PWM techniques, including sinusoidal PWM, zero-sequence injection PWM, third-harmonic injection PWM, space vector modulation, and optimized pulse pattern with selective harmonic mitigation.
PWM inverters can be broadly categorized into single-phase and three-phase types, each with distinct structures and applications. Single-phase PWM inverters consist of two main parts, the DC power source and the inverter bridge, typically use a full-bridge configuration consisting of four power switches, usually IGBTs and MOSFETs.
