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.
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.
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.
PWM enables precision in wave generation and power quality and provides efficient harmonic suppression. Through the modulation of the width of the voltage pulses, the desired AC waveforms in high-voltage inverters can be approximated for an efficient and smooth power flow to the loads.
