摘要
提出了逆变器并联或冗余并联系统中基准信号同步的一种方法 ,实现逆变器模块直接并联(系统不附加额外的控制模块、分散在各模块中的基准电路自动同步 )、模块热插拔 ,又不影响逆变器单机工作。研究了该方法的具体实现电路及工作原理 ,进行了定量误差分析 ,并给出了仿真和实验结果。
A synchronous method for reference input of redundant parallel inverter systems is presented. Using the processing method, the inverters can work alone or be directly connected together to perform parallel operation without extra control unit, and the output of the circuits distributed in every inverter automatically synchronize as reference signals, and furthermore on line replacement of inverters in parallel operation is allowed. Circuit realization, principle and synchronous errors are analyzed. Finally, simulational and experimental results are given.
