6 FAQs about [Three-phase sinusoidal pwm voltage inverter]

What is a three-phase voltage source inverter (VSI) with SPWM?

A three-phase Voltage Source Inverter (VSI) with SPWM (Sinusoidal Pulse Width Modulation) is a type of inverter that converts DC voltage into three-phase AC voltage with sinusoidal waveforms. It works by varying the pulse width of a high-frequency carrier signal according to the instantaneous amplitude of a reference sinusoidal waveform.
