Capacitive leakage current is one of the most important issues for transformerless photovoltaic systems. In order to deal with\nthe capacitive leakage current, a new power electronic inverter circuit is proposed in this paper. The inverter circuit consists of\nsix switches and operates with constant common mode voltage. Theoretical analysis is conducted to clarify the circuit operation\nprinciple and the common mode characteristic. The performance evaluation test is carried out, and test results demonstrate that\nthe capacitive leakage current can be significantly minimized with the proposed power electronic inverter circuit.
