本人自制了一简单充电器,不仅充电电流可调,而且充满后自动断电,使用两年来一直很好。 一、充电原理 如图所示,当需要充电的电瓶的“+”“-”极接入电路时,先将w1左旋到底,再打开电源开关,然后按下AN按钮,JA动作,JA-1吸合而自锁;JA-2接通充电电路。以36Ah铅蓄电瓶为例。慢慢调整W1改变BT33的振荡频率,从而改变单向...
一、电路设计 在蓄电池充电完成后,充电器指示灯由红色变为绿色然后再充一小时到两小时为宜,因此,该电路包含有充电完成检测电路,长时间延时电路和开关驱动电路等,如图1所示。 由于充电是否完成是通过指示灯颜色来判断的.因此检测电路可由光敏电阻来完成。因充电时间较长,要有足够的精度,所以延时电路采用基准时钟加计数...
