摘要
采用交错并联Boost PFC变换器和移相全桥变换器,分析了一种高功率因数可调直流开关电源的设计方案。设计并调试了一台2.2 k W的试验样机。样机输入功率因数、效率高,充分验证了设计方案的可行性,在大功率应用场合具有良好的应用前景。
This paper advanced a design scheme of adjustable DC switching power supply,taking advantage of interleaving Boost PFC and phase-shifted full bridge（ PSFB）. An experimental prototype which has high power factor and high efficiency was built and verified the design scheme. The design scheme will have favorable application prospect.
