摘　　要：通过采用无桥PFC和半桥LLC谐振变换器作为数字开关电源的主变换拓扑,基于STM32系列微控制器的全数字控制PFC和DC-DC变换器,首先对数字化开关电源方案进行对比,然后阐述了200W数字开关电源整体方案,并对数字开关电源的无桥PFC和半桥LLC变换器进行系统研究。By using a bridgeless PFC and a half-bridge LLC resonant converter as the main conversion topology of the digital switching power supply,the all-digital control PFC and DC-DC converter based on the STM32 series of microcontrollers,firstly the digital switching power supply scheme is compared,and then the overall scheme of 200 W digital switching power supply is expounded, and the bridgeless PFC and half-bridge LLC converter of digital switching power supply are systematically studied.

关 键 词：无桥PFC LLC谐振电路 STM32系列微控制器 全数字控制
