基于單片機的智能充電電源設計

摘要：通過分析蓄電池常規(guī)充電方法的不足，采用多段式充電的充電策略，以ADUC814單片機和SG3525作為主控芯片，設計了以全橋變換為主電路結構的充電電源硬件電路和軟件系統(tǒng)。樣機試驗波形表明,該智能充電電源設計方案合理，輸出的電壓紋波小，穩(wěn)定性高，具有較好的實用價值。

The power supply design chose the ADUC814 microcontroller and SG3525 as the master control chip. Paper designed the software system and hardware circuit that by full-bridge converter as the main circuit structure. Prototype test waveforms show that the charging power supply design is reasonable, the output voltage ripple is small, and the stability is high. The intelligent charging power supply has good practical value. Keyword：Keywords: Single chip , Charging power supply , SG3525 , DC Convert
