| 摘 要： | 三相整流桥装置产生的电力谐波具有谐波含量大，谐波频谱分布宽的特点。直流侧有源电力滤波器是针对整流桥装置提出的谐波治理方案。本文从频域角度对三相直流侧APF的补偿性能进行研究，定量分析了电流环带宽与谐波补偿效果的关系。并与传统交流侧APF进行了对比分析，在对相同的整流桥负载进行谐波补偿时，三相直流侧APF的补偿性能明显优于交流侧APF。最后采用平均电流控制策略，完成了三相直流侧APF的设计，并通过实验结果验证了理论分析的正确性

| Abstract: | The input current of three-phase rectifier has a large range of high-frequency harmonic components. DC link APF is paralleled at dc side of the rectifier and is functioned to suppress the input harmonic current of the rectifier. Compensation performance of three-phase DC link APF is researched in this paper at frequency-domain. Quantitative analytical results are obtained to express the relationship between current controller bandwidth and THD of the input current. The result indicated that, comparing with the conventional AC link APF, the three-phase DC link APF has much better compensation performance for the same three-phase rectifier load. Based on the performance research, three-phase DC link APF with dual-loop average current control is designed to suppress the rectifier harmonic current. Experimental results are presented to verify the correctness of the research |
