  • 一種車載充電器的設計

    以AT89S52單片機為控制核心,采用電容降壓技術,Buck電路拓撲,PWM驅動模塊和功率器件散熱設計,通過高速的數據采集、主功率輸入輸出模塊和控制模塊,設計一種新型智能車載充電器.在充電過程中,通過負脈沖瞬間放電實現對鉛酸蓄電池的再生修復,提高電池的有效容量,延長使用壽命.該充電器體積小、速度快、效率高、可靠性好.With AT89S52 single chip computer as the control core,a new type of intelligent car-carried charger was designed by using capacitance step-down technology,Buck circuit topology,PWM driving module and power device heat dissipation design,through high-speed data acquisition,main power input and output module and control module.In the charging process,the regeneration and repair of lead-acid batteries are realized by instantaneous discharge of negative pulse,which improves the effective capacity of batteries and prolongs their service life.The charger has the advantages of small size,fast speed,high efficiency and good reliability.
