This paper proposes a closed-loop Global Synchronous Pulse Width Modulation (CL-GSPWM) method for attenuating circulating leakage current in PV station with many inverters connected in parallel. The CLGSPWM can well minimize leakage current without central calculation and the pre-known parameters of each inverter, such as leakage capacitors, feeder impedance, etc.. Each inverter can control its PWM phase shift angle to minimize the leakage current with the measured leakage current. Meanwhile, it only needs to transmit little information among inverters, which means the proposed method can be integrated into inverter without additional hardware. Experimental prototype with four down-scale inverters are employed to verify the performance of the proposed CLGSPWM.
