The zero-sequence circulating current does not participate in the AC-DC power conversion of the parallel system, but is only the parasitic loss of the parallel system, which reduces the system energy conversion efficiency [4]-[7].
The zero sequence circulating current does not participate in the AC / DC power conversion of the parallel system, but only the parasitic loss of the parallel system, reducing the energy conversion efficiency of the system [4] - [7].
