How to avoid circulating current in photovoltaic inverters
The circulating current can be avoided by providing galvanic isolation between the parallel VSCs using multiple winding line frequency transformer [6], [7]. The proposed control structure contains n − 1 zero-sequence control loops, with n being the number of inverters connected in parallel. . However, when the inverters share a common DC source and AC bus, a circulating current is generated, which causes output current distortion and system power losses. In this paper, the solutions, including hardware and software, are proposed to suppress the ground current.Read More Download PDF
