| 摘要: |
| 针对大功率有源滤波器的研究成果，提出了一种实现大容量有源滤波器的主从式结构方案，并设计了与之相适应的控制方案。为了避免两个变换器直流侧之间的耦合作用，两个变换器的直流侧相互独立。辅助变换器采用常见的直流电压闭环控制，而主变换器能根据负载无功功率的要求自动调节并采用斩波控制以保持两个电容器之间的电压平衡。仿真和实验证明具有主从式结构的有源滤波器具有良好的补偿性能。 |

| Abstract: |
| Based on the study of high-power APF(Active Power Filter), a master - slave mode scheme for it is proposed and the corresponding control scheme is designed. The DC sides of two converters are independent to avoid coupling between them. The slave converter adopts general DC voltage closed loop control,while the master converter automatically adjusts the reactive power according to the demand of loads and adopts chopping control to keep voltage balance between two capacitors. Simulation and experiment results show that the proposed APF has good compensation performance. |
