摘要
采用了一种检测负载侧与电源侧电流的复合谐波电流检测方法,针对四桥臂拓扑结构的有源电力滤波器(APF),提出了一种新型无差拍控制策略,通过对系统结构的分析建立完整的数学模型,对APF各相输出补偿电流之间的耦合问题进行深入研究并提出相应的解决方法。仿真分析和实验结果验证了复合谐波电流检测算法和无差拍控制策略的有效性和正确性。
A compound harmonic current detection of the active power filter（APF）,including the load current detection and the source current detection is proposed.A novel deadbeat control strategy is proposed for the APF with four-bridge topology.Based on the analysis of the topology of the system,a complete mathematical model is established.The coupling a-mong the output harmonic currents of every phase in the APF is analyzed,and the decoupling method is presented.The simulation and experimental results demonstrate the effectiveness of the proposed compound harmonic current detection method and the deadbeat control strategy.
