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.
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 concept of Pulse Width Modulation (PWM) for inverters is described with analyses extended to different kinds of PWM strategies. Finally the presented. battery or rectifier provides the dc supply to the inverter. The inverter is used to voltage. AC loads may require constant or adjustable voltage at their input terminals,
Table 2.1 provides an overview of inverter categories. Voltage-type PWM inverters are most commonly used. These inverters are further divided into two categories, depending on the commutation method used: 120° commutation primarily used for small motor applications and 180° commutation used for many motor and power supply applications.
