Abstract
The utility model discloses a program-controlled pulse compensation type charger. A power supply unit converts alternating current into direct current and outputs the direct current to supply power to and charge a battery. A control unit in the power supply unit, according to a voltage value feedbacked by a photoelectric coupling unit, performs pulse width control on a switching switch, and further controls signal pulse width input into an input end of a transformer and regulate output pulse width of the transformer so as to supply power to different loads. A charging control unit controls the entire charging state through a microprocessor, and through magnitude of current sampling and duration of charging, detects a current state of the charging of the battery, and according to charging state switching signals, performs switching of constant current charging and pulse charging. Therefore, according to the charger, the charging can be precisely controlled, and service life of the battery can be prolonged.
