摘要
在分析双电感半桥电路的基础上,提出了一种基于改进半桥拓扑结构的新型有源电力滤波器,它消除了传统有源滤波器拓扑的桥臂直通故障隐患,且具有可高频、高效率运行的优点。文章详细分析了其工作原理,给出了相应的控制策略。仿真和实验结果验证了这种新型有源滤波器的可行性。
Via the analysis of double-inductance half-bridge circuit, a novel active power filter was introduced based on improved half- bridge topology, which can eliminate the hidden faults of bridge arm shoot-through in traditional active power filter topology. It has advantages of high frequency and high efficiency. The operating principle was analyzed in detail, and the corresponding control strategies were given. The simulation and experimental results verify the feasibility of the novel active power filter.
