| 摘 要： | 当并联的逆变器共直流电源时，若各台逆变器的参数不一致将会引入零序环流，文中首先建立了零序环流的数学模型，并提出了相应抑制零序环流的控制策略，最后在两台共直流电源的三相逆变器并联系统中给出了相应的仿真分析结果。

| Abstract: | Zero-sequence circulating current will exist when the parameters of paralleled inverters with the same DC link differentiate. Firstly the mathematical model of zero-sequence circulating current is established in this paper, then the corresponding control scheme of rejecting zero-sequence circulating current is presented, and the simulated results are presented for two-paralleled three-phase inverters with the same DC link in the end. |

| Keywords: | inverter zero-sequence circulating current with the same DC link space vector dead time |
