A perfect solution to completely eliminate leakage currents in PV systems is through specific topologies and/or modulation techniques that maintain the CMV constant or equal to zero. This paper presents a modified configuration with symmetrical six switches based on the common ground. . The inverter topology proposed in this paper changes DC power from solar panels into AC power and supplies it directly to the grid. Additionally, it keeps grid voltage and current total harmonic distortions (THDs) below 1%, reduces leakage current to nearly zero, and significantly improves power. . These inverters are different in their size, cost, boosting capability, the possibility of producing DC currents, and their capability to offer multilevel shaping of output voltage. Therefore, a. . Abstract—The zero-crossing distortion (ZCD) is a common problem in Single-phase transformerless photovoltaic (PV) inverter. An improved inverter circuitry is presented which works on low input same as full bridge inverter and insure the elimination of common-mode. .
