摘　　要：针对电流源型变频器中存在的大量谐波.在电流型变频器的基础上加入一个电压型逆变电路,提出了一种谐波电流的补偿方法。该方法首先通过滤波电路检测谐波电流.然后补偿电路产生与谐波电流相位相反的电流注入负载.以减小负载电流谐波.此外.补偿电路还可以提高变频调速系统运行性能以及可靠性.It is proposed to add a compensation circuit into the traditional current source converter to reduce its harmonics produced by the current source inverter. The current harmonics of current source converter is analyzed with the case of single phase and the appropriate value of compensation circuit is chosen. When the compensation circuit and that CSI inverter side are connected together, the current harmonic is well restrained. Further more, the hybrid converter can improve the system stability. Simulative results verify the correctness of the theoretical analysis.
