本文提出了一种具有有源电力滤波功能的降压型单相PFC-AC/DC变流器的改进电路拓扑，该电路具有电抗器体积更小、重量更轻、输出电压纹波系数最小的特点。此外，该有源PFC-AC/DC转换器还可以在没有任何带有电流传感器接口的特定反馈控制方案的情况下抑制公用事业交流电网中的电流谐波。这里讨论的电路配置更适合于各种应急电源以及电信电源，其中抗雷击尤其被认为在48V-10A输出规格下更有效。本文介绍了所提出的功率MOSFET AC-DC变换电路的工作原理及其控制实现，并给出了仿真和实验结果及其评价。文中给出了扩展的PFC-AC/DC转换器的拓扑结构，它们工作在所提出的控制方案下。
This paper present an improved circuit topology for a buck chopper type single phase PFC-AC/DC converter with active power filtering function, which has smaller in reactor size and lighter in its weight, and can minimize the DC output voltage ripple factor. In addition, this active PFC-AC/DC converter can be also suppressed the current harmonics in utility AC grid without any specific feedback control scheme with current sensor interface. The circuit configuration treated here is more suitable for a variety of emergency power as well as telecommunication supply, where the lightning resistance is particularly considered to be more effective for 48 V-10 A output specification. In this paper, the operating principle of proposed AC-DC converter circuit using power MOSFETs and its related control implementation are described, along with its simulation and experimental results and their evaluations. The extended PFC-AC/DC converter topologies are demonstrated, which are operating at the proposed control scheme.
