摘要 传统并网变流器使用固定前馈来解决启动冲击电流问题,能量转换系统(PCS)由于直流侧接电池,直流电压范围宽,采用固定前馈无法在全直流电压范围内抑制启动冲击电流。对PCS主电路拓扑、控制方法进行了介绍,提出一种抑制PCS启动冲击电流的方法,仿真和实验证明该方法可有效抑制PCS启动冲击电流。 The conventional grid converter uses fixed feedforward to solve the inrush current issues at startup.Power conversion system (PCS) due to the DC side connected batteries, with a wide range of DC voltage, fixed feedforward can not suppress inrush current in the whole DC voltage range.The PCS main circuit topology,control methods are introduced,a method for suppressing the inrush current at startup is proposed.Simulation and experimental results show that the method can effectively suppress the inrush current of PCS at startup.
