The diode-assisted Cuk Voltage Source Inverter (VSI) enhances the voltage boost capability which is more suitable for wide range voltage regulation in dc/ac power conversion. This paper mainly describes Pulse-Width Modulation (PWM) strategy for diode-assisted cuk VSI. Compared with existing buck-boost converter, diode-assisted capacitor cuk VSI with SVPWM strategy demonstrates good performances like less switching device requirement and higher efficiency at high voltage gain. The proposed diode-assisted cuk VSI is more advantageous and competitive topology for wide range dc/ac power conversion in a renewable energy application. Simulation model of SVPWM is obtained using MATLAB/SIMULINK.
