摘要：

Leakage current reduction is crucial for operating transformerlss photovoltaic (PV) systems. In this letter, a new three-phase topology and modulation strategy is proposed. It is derived from the single-phase zero-voltage state rectifier topology, but the operation mechanism is quite different. Therefore, a new modulation strategy based on the Boolean logic function is proposed to achieve the constant common-mode voltage, so as to eliminate the leakage current. Finally, the experimental tests are carried out to verify the feasibility and effectiveness of the proposed solution.
