摘　　要：多逆变器并联是提升逆变器容量、增强舰船大功率负荷承载能力的重要途径。然而,多个并联逆变器输出电压的不一致性会导致逆变器之间形成环流,影响输出电压电能质量并降低负荷供电可靠性。对此,提出了一种基于FC-AE的逆变器并联同步控制方法,该方法采用光纤通信传递各逆变器间的同步信号,考虑了通信线路长度差异带来的延时误差并设计了补偿方案。最后,仿真和试验结果表明提出的方法可以实现多逆变器输出电压相位的高精度同步,显著抑制了并联逆变器之间的环流。Multiple inverters in parallel is an important way to increase the capacity of inverters and to enhance the carrying capacity of high-power loads of ships.However,the inconsistency of the output voltage of multiple parallel inverters can lead to the formation of circulating current between the inverters,which will affect the power quality of the output voltage and reduce the reliability of the load power supply.In this paper,a parallel inverter synchronous control method based on FC-AE is proposed,which adopts optical fiber communication to transmit the synchronous signals between inverters.The delay error caused by the difference in the length of the communication line is considered,and a compensation scheme is designed.The results of simulation and experiment show that the proposed method can achieve high-precision synchronization of the output voltage phases of multiple inverters,which significantly suppresses the circulating current among the parallel inverters.
