一种基于复合控制的逆变电源并联技术的研究

研究了基于重复控制的复合控制策略。复合控制不仅保留了重复控制消除周期性波形畸变的能力，同时大大提高了系统的动态响应速度。采用一种能实现瞬时值均流的分布式并联控制方法完成逆变电源系统的模块并联。通过连接各完全等同的并联模块中的三条低频信号总线实现均流。只用一个调节器，既调节输出电压、同时又实现环流抑制。应用数字化控制成功地进行了系统试验，并对关键的试验波形做出了分析。

Research on Parallel Connected Inverter Based on Multiplexed Control Strategy

In this paper,multiplexed control strategy based on repetitive control is applied. The harmonic distortion of output voltage wave is reduced and inverter dynamic response characteristic is improved by this strategy. A distributed parallel control scheme with instantaneous current sharing is developed for redundant parallel inverter power supply system. Current sharing based upon the average current method is realized by using a shared bus to connect all the parallel modules without extra control modules. Th...
