摘要
基于航空电网高可靠性的要求,提出一种新型三相四线并联型有源电力滤波器(parallel active power filter,PAPF)。该拓扑的桥臂均为单功率管单二极管结构,替代了传统桥式功率电路中双功率开关管串联的桥臂,从根本上杜绝了其桥臂直通隐患,并且这种结构利于有源滤波器系统效率及其补偿性能的提升。详细分析其工作原理,研究适宜的电流控制策略和直流侧分裂电容均压控制的实现。设计了一台3kVAAPF的系统参数。仿真和实验结果验证了新型并联有源滤波器系统的有效性和可行性。
In order to fulfill the high reliability of the aeronautical application,a novel three-phase four-wire parallel active power filter was proposed in this paper.In this proposed configuration,traditional leg composed of two power switches was replaced by the novel bridge composed of one power switch and one diode.The annoying ＂shoot-through＂ phenomenon was eliminated by using this configuration.Meanwhile,the better efficiency and better performance brought by this novel configuration benefit the improvement of the compensation performance.Moreover,operation principle of the APF was analyzed in detail;current control strategy and the voltage balance control strategy for the split-capacitor topology were studied as well.Finally,a prototype with the load power of 3 kVA was designed.Simulation and experimental results were shown to confirm the validity and feasibility of the novel aeronautical active power filter.
