| 摘 要： | 变流器并联是进行变流器扩容的主要方式之一,文中研究了影响三相并网变流器并联应用中各模块输出电流一致性的各种因素。在建立了多变流器并联系统模型的基础上,通过理论分析与数学推导,给出了电流一致性与各模块参数之间的关系表达式。通过仿真以及对包含两套容量为260kVA的有源电力滤波器并联系统进行实验,验证了理论分析的正确性。

| Abstract: | Converter paralleling is a main approach to expand capacity. This paper analyzes factors impacting on current consistency of parallel converters. On the basic of establishing system model, expressions of relationship between current consistency and relative parameters are obtained through theoretical analysis and mathematical derivation. Simulations and experimental results on an active power filter which paralleled by two 260kVA converters verify the correctness of theoretical analysis. |

| Keywords: | PWM converter parallel system dead-time impedance consistency |
