This work proposes a FPGA Based Multilevel Inverter with Reduce Number of Switches for Photovoltaic System. Three sorts of reference flags that are indistinguishable to each other with a counterbalance that is equal to the amplitude of the triangular transporter were utilized to create the PWM signals. The inverter can deliver seven levels of yield voltage levels (Vdc, 2Vdc/3, Vdc/3, 0, - Vdc, - 2Vdc/3, - Vdc/3) from the dc supply voltage. An advanced PI current control calculation was executed in a Xilinx XC3S250E FPGA to keep the current infused into the framework as sinusoidal. The proposed framework was composed and checked through recreation and executed in a model.
