Modern appliances are mostly running on AC power and three-phase voltage source inverter is utilized to convert DC power to three-phase AC power. In order to generate true sine wave, SPWM switching technique is adopted in this paper with closed-loop mechanism where output voltage and current are controlled simultaneously.
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.
A three-phase voltage source inverter is connected to proposed converter which converts the DC power obtained from proposed converter into AC power. The proposed inverter output has reached its expected value for three-phase applications without further stepping up the voltage using transformer as the converter output voltage is high enough.
Close-loop control feedback path withstands the source voltage variation. The proposed converter simulation result gives controlled output voltage of 750 V (Fig. 23.5 ). Three-phase voltage source inverter is used with sinusoidal pulse width modulation (SPWM) switching technique.
