Which PWM techniques are used in two-level voltage source inverters?

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?

An inverter whose functionality depends upon the pulse width modulation technology is referred to as PWM inverters. These are capable of maintaining the output voltages as the rated voltages depending on the country irrespective of the type of load connected. This can be achieved by changing the switching frequency width at the oscillator.

What is a pulse width modulation (PWM) inverter?

Pulse Width Modulation (PWM) inverters offer several significant benefits over traditional square wave inverters: Precise Control: They provide exceptional control over output voltage and frequency, which is crucial for sensitive electronic devices and efficient motor control.

What is PWM in a VSI?

With PWM, a fixed DC input voltage source can produce a sinusoidal output waveform with variable frequency and amplitude. PWM methodologies in inverters provide fine control over the output voltage waveform in VSIs, enabling accurate voltage regulation as well as current regulation.
