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.
Three-phase Inverter Bridge A three-phase two level inverter consists of three power electronic switches (Transistors), two in each leg for each phase of motor winding. The switches in each leg are driven by complementary pulses to switch the phase voltage between positive and negative DC voltage.
To implement V/F control, the ratio of voltage (V) to frequency (F) can be kept constant by adjusting the frequency and amplitude of the three-phase induction motor . Building upon V/F control, we have developed a model of a three-phase PWM inverter.
