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.
In a 3-phase inverter, three separate SPWM signals are generated for each phase, By comparing a high-frequency triangular waveform with three sinusoidal reference waveforms (one for each phase) to determine the pulse widths of the inverter''s switching devices.
phase inverter is used to provide variable frequency power for industrial applications. SPWM is used for the voltage con rol of three phase inverters and the corresponding gating signals are shown in Figure 3. Here, triangular carrier wave is c ared w th three referen
