摘要
提出一种新型基于光纤环网的三相逆变器并联拓扑结构。整个系统由1个中央控制器和3个底层控制器构成。底层控制器通过光纤环网将采集的数据上传给中央控制器,中央控制器再将计算结果通过光纤环网传输给底层控制器,底层控制器还负责各个模块驱动脉冲的同步。建立了系统在同步旋转坐标系下的数学模型,给出了并联系统的控制策略,设计了系统的双环控制器。实验结果表明该拓扑结构简单,可行性高。
A new parallel topology of three-phase inverter system based on fiber ring net is proposed.The system has one central controller and three device level controllers.The device level controllers transmit the data they collected to central controller through the fiber ring net, then the central controller transmits the calculated results to device level controllers through the fiber ring net.The device level controllers are also designed to make driving pulses synchronized. The model based on synchronous rotating coordinates is analyzed.The control strategy for the parallel system and the double-loop controller are designed.Experimental results prove that the proposed topology is effective and easy to design.
