This section elaborates the pulse width modulation (PWM) control methods of voltage source inverters (VSIs). The Sinusoidal PWM (SPWM), Third harmoic injection PWM (THIPWM) and space vector PWM (SVPWM) are discussed and compared. With PWM, a fixed DC input. . The fundamental magnitude of the output voltage from an inverter can be external control circuitry is required. High-voltage inverters form an essential part of renewable energy systems, and. . Lessons-36 and 37 have dealt with PWM inverters. As pointed out in these lessons, the two main advantages of PWM inverters in comparison to square-wave inverters are (i) control over output voltage magnitude (ii) reduction in magnitudes of unwanted harmonic voltages. The technology of PWM plays a pivotal role in enhancing efficiency, minimizing harmonics, and improving voltage regulation in inverters.
