一款6V“千里眼”充電器電路設計

發布日期:2022-04-17 點擊率:63

【導讀】本文為大家接受介紹一款6V千里眼充電器電路設計,具體的電路設計請看下文電路圖展示,和詳細的電路工作原理解說。

 

“千里眼”充電器電路如圖所示。其中單向晶閘管 VS1為電瓶GB的充電電流管,VS2為電瓶充電時作切斷充電電流之用。當接通電源充電時,繼電器K動作,觸點3與觸點2接通,VS1的觸發端從R1和 VD4取得觸發電壓而導通,整流電流通過VS1向電瓶GB充電。當電瓶GB充電到設定的電壓時(例如7.2V),VS2導通,導致VS1觸發端A點電位大大低于VS2的陰極電位,VS1截止,電瓶GB停止充電。發光管LED作充電顯示用,電瓶充電停止、VS2導通時,LED熄滅。6V指示燈HL 作~220V停電指示用。
