摘　　要：单周控制直流侧有源电力滤波器不需要检测负载电流、不需要计算负载电流的谐波和无功分量、不需要乘法器,具有主电路结构新颖、控制电路简单以及补偿效果好等优点。在深入分析单周控制直流侧APF的基础上,提出了一种上升沿调制的单周控制直流侧APF,相比较传统的下降沿调制单周控制直流侧APF,控制电路更为简单,仿真结果验证了理论分析的正确性。The one cycle controlled （OCC） DC side APF is no need to sense the load current, no need to calculate the harmonic and reactive component of the load current,and no need for the multiplier. It has the property of new main circuit structure, simple control circuit and good compensation. A leading-edge modulation OCC DC side APF based on the analysis of OCC DC side APF is proposed. Its circuit is simpler than the traditional trailing-edge modulation OCC DC side APF,the proposed theory and circuit are verified by simulation results.
