| 摘 要： | 逆变电源的并联运行是提高电源系统容量和可靠性的有效手段。该文分析了逆变电源并联运行原理，提出了抑制并联系统环流的3种控制策略。在此基础上，针对采用SVPWM的三相逆变电源，提出了三相系统的分散逻辑控制方案。该方案成功的应用于2台35kW、390V、50Hz三相逆变电源组成的并联系统中。实验结果证明，逆变电源并联系统在该方案下可有效的实现负载均分。

| Abstract: | The principle of the parallel operation of the inverters is analysed. Three control strategies for restraining the circulating current existing in the parallel system are proposed. The distributed logic control strategy for the three-phase inverter parallel system is presented. This strategy has been successfully applied to the power system where two three-phase inverters, each of them 35kW, 390V, 50Hz, operate in parallel. The load sharing is satisfactory. |
