摘要
文中对无源式PFC、两阶段型PFC、单级型PFC技术进行比较，然后采用单端反激式变换器拓扑，设计了一款60w路灯的驱动电源，通过实验结果分析，该实验验证了理论分析的正确性和可行性，达到了较好的功率因数校正效果，具有较强的实用性和优越性。
This paper compare the passive PFC and two-stage PFC, single stage type PFC technology, then the single-stage power factor correction technique for the design scheme based on single ended- flyback converter topology, design a 60 W lamp driving power supply, through the analysis of experimental results, the experiments verify the correctness and feasibility of the theoretical analysis, reach the better effect of power factor correction, with strong practicality and superiority.
