Use the charger of common charger circuit on the market owing to can not cut off the power supply fully for a long time, the power consumption that is in the trickle saturation condition like this after the no-load power consumption of charger and the charging becomes fairly obvious.The no-load power consumption of charger that uses common charger circuit on the market as 30mA-50mA about, every month consumed power reaches 0.9KW.h---1.5KW.h at least like this, as so just exist huge waste of energy, so also influence the useful life of whole charger.It is a few μ A or tens μ A that also still there is very little no-load current in present so-called intelligent power saving charger on the market in fact.
The utility model content
Based on the deficiencies in the prior art, the purpose that the utility model is created is to provide the charger circuit of the unloaded zero-power of a kind of real realization.Waste of energy can be reduced so on the one hand, the useful life of charger can be prolonged on the other hand.
To achieve these goals, the utility model provides a kind of charger circuit, it is characterized in that being formed by three parts, first is the switch key circuit, second portion detects load circuit by switching power circuit and two diode in series and forms, third part is the FEEDBACK CONTROL partial circuit, the switch key circuit of described first and the switching power circuit of described second portion are connected in series, the switch key circuit of described third part FEEDBACK CONTROL partial circuit and described first is connected in series, and the switching power circuit of described third part FEEDBACK CONTROL partial circuit and described second portion is connected in series.
As the improvement of the utility model charger circuit, it is characterized in that described first switch key circuit forms power supply Push And Release circuit by starting button and controllable silicon BT131, only open the startup button, power supply is just powered.
Improvement as the utility model charger circuit, it is characterized in that described third part FEEDBACK CONTROL partial circuit, mainly be made up of an optocoupler OP01 and triode Q01, its main effect is will cut off controllable silicon when not connecing load and stop power supply when detecting, and reaches energy-saving effect.
[0007]Compared with prior art, the utlity model has following beneficial effect.
1, this charger circuit can reduce waste of energy.
2, can prolong the useful life of charger.
