| 摘 要： | 提出一种单相输出可调压的新型直流侧串联型有源电力滤波器(active power filter,APF),对单相整流类负载进行功率因数校正和谐波治理有很大的技术优势。从理论上分析了改进型直流侧APF的电路拓扑和基本工作原理,给出了主电路的主要参数设计和选取标准,为系统的综合设计提供了理论依据。与传统的交流侧串联型APF相比,该APF串联在整流桥的直流侧,简化了电路结构,减少了有源开关的数量;与直流侧串联型APF相比,该改进型APF实现了输出电压的可调,简化了相应的控制和驱动电路,进一步减小了储能电容容量。仿真和实验结果证明了所提出拓扑的正确性和可靠性。

| Abstract: | An improved series single-phase active power filter (APF) at DC side whose output voltage is adjustable is proposed,this kind of improved APF can perform power factor correction and harmonic elimination for single-phase rectifier load. The circuit topology and basic working principle of the proposed improved series APF are analyzed theoretically; the design of main parameters and their selection are given. The proposed improved APF is connected in series with rectifier bridge at its DC side,so the circuit s... |
