通過采用無橋PFC和半橋LLC諧振變換器作為數(shù)字開關(guān)電源的主變換拓撲,基于STM32系列微控制器的全數(shù)字控制PFC和DC-DC變換器,首先對數(shù)字化開關(guān)電源方案進行對比,然后闡述了200W數(shù)字開關(guān)電源整體方案,并對數(shù)字開關(guān)電源的無橋PFC和半橋LLC變換器進行系統(tǒng)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.
