The use of transformerless Photovoltaic inverters is increasing day by day, because of benefits of achieving lower cost, smaller volume, higher efficiency compared to ones with transformer inverters. The transformerless inverters eliminate the leakage current from the circuit. In addition to this, according to international regulations, transformerless inverters should be capable of handling a certain amount of reactive power. In this paper the H6 topology is proposed by using Inverted sine pulse width modulation (ISPWM). The results are compared with traditional sinusoidal pulse width modulation (SPWM). The proposed topology is simulated using MATLAB simulink software.
