One of the major problems of solar photovoltaic panels is capacitive ground current. Because of the bulk size, higher cost and lower efficiency due to using transformer to solve the problem so in this paper a transformer-less inverter topology and a proper control strategy is proposed to suppress the ground leakage current caused by inverter switching and varying common mode voltages. The operation of the proposed topology and control strategy is simulated using Cadence ORCAD software and a prototype of experimental circuit elements and PCB of the proposed topology and control strategy is designed and implemented using Proteus software.
