Resumé

Leakage current reduction is crucial for operating transformerlss PV systems. In this letter, a new three-phase topology and modulation strategy is proposed. It is derived from the single-phase ZVR (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.
