Photovoltaic energy is one of the ruling area due to it’s easy availability and pollution free nature. At the same time the voltage from the PV is needed to be stepped up for different load requirements. There are various pulse width modulation techniques for the control of impedance Source inverter(ZSI).Here we have considered Carrier based various PWM techniques for PV-ZSI Converter. The proposed converter consists of cascade connection of PV Modules and Conventional-ZSI which provides higher boosting factor and smaller size than that of existing VSI .The performance of inverters depend on the type of modulation technique used to switch them. This work depicts a detailed analytical approach in MATLAB/Simulink platform as well hardware consists of sine triangle PWM method for proposed new topology PV-ZSI. It has been observed output voltage of proposed inverter is more in comparison to conventional VSI. As the proposed inverter is lesser in size and output voltage is greater so it is more efficient than conventional VSI. There is no requirement of Boost converter .
