Three-phase PWM inverters have a similar operating principle to single-phase inverters but use six power switches arranged in three legs. The control unit generates three separate PWM signals, one for each phase. These signals are used to control the switching of the IGBTs to produce three-phase AC power.
In this paper, the main achievement of the three-phase PWM inverter is main circuit design, including the rectifier circuit, filter circuit, an inverter, a drive circuit and a control circuit design, completed the selection of the relevant device, the basic realization of AC-DC-AC conversion function. (Your comment will show after approved.)
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.
c). PWM inverter circuit features: you can get quite close to the sine wave output voltage and current, it is also known sinusoidal pulse width modulation SPWM (Sinusoidal PWM). d).
