摘要

本文提出了一种带漏能回收电路的120W单级PFC LED驱动器。三个降压升压衍生变换器集成，他们只利用一个共同的有源开关。第一个降压-升压变换器用从电网中提取的单位功率因数来调节正弦输入电流。第二个反激变换器控制提供给led的直流电流。另一种buck-boost转换器取代了传统的RCD缓冲器，进一步提高了能源效率。所有的变换器都设计成在断续电流模式下工作。详细讨论了其工作原理、电路分析和控制器设计。给出了一个120W LED驱动器的设计实例。通过PSIM 10软件验证了所提出的拓扑结构。仿真结果表明，该电路能够在较宽的范围内调节LED输出电流。可实现统一的功率因数和低谐波电流畸变。

Design of a single stage PFC LED driver with a leakage energy recycling circuit

In this paper, the 120W single stage PFC LED driver with a leakage energy recycling circuit is proposed. Three buck-boost derived converters are integrated and they utilize only one common active switch. The first buck-boost converter regulates the sinusoidal input current with unity power factor drawn from the grid. The second flyback converter controls essentially DC current supplied to the LEDs. The other buck-boost converter replaces a conventional RCD snubber to further improve energy efficiency. All converters are designed to operate in discontinuous current mode. Operation principle, circuit analysis, and controller design are discussed in detail. Design example if a 120W LED driver is presented. The proposed topology is verified by software PSIM 10. The simulation results show that it is capable of regulating the output LED current over a wide range. Unity power factor and low harmonic current distortion can be achieved.
