Description
Technical field
The present invention relates to charger control system field, particularly relate to a kind of portable adjustable voltage charger control system.
Background technology
Charger is a kind of product often used during people live, because we often need to various equipment charge or power supply, so sometimes need to carry with charger.Especially in the society that this electronic product is propagated its belief on a large scale, this demand is more fanatic.Charger is in the market generally producer first wife, can only be applicable to a kind of product, and computer charger just can not charge the phone.So multiple charger may be needed when we are away from home, inconvenience very.If the charger of various producer can be incorporated into above one, and charging effect is good, very large welcome will be subject to.
In sum, lack so a kind of charger at present, volume is little, lightweight, can carry with; Output voltage stabilization, operating efficiency is high, generates heat little; Cost is low as much as possible, can export various magnitude of voltage, and is that people is manually adjustable, and magnitude of voltage can clearly show.
Summary of the invention
Technical problem to be solved by this invention is the deficiency for general charger, there is provided one can random regulation output voltage, and output voltage is shown, small in volume, can carry with, output voltage stabilization, operating efficiency is high, generate heat little, cost is low, the charger control system that voltage people is manually adjustable.
The present invention solves the problems of the technologies described above taked technical scheme: a kind of portable adjustable voltage charger control system, comprise 12C5A60S2 single-chip microcomputer, high-power switch tube, Switching Power Supply driving chip, voltage sampling circuit, display charactron, rectifier bridge and transformer, transformer is connected with electric consumption on lighting by input interface, and rectifier bridge is connected with transformer and realizes Transformer Rectifier effect; Switching Power Supply driving chip is connected with 12C5A60S2 single-chip microcomputer and high-power switch tube, Switching Power Supply driving chip two ends connect input filter circuit and output filter circuit respectively, input filter circuit is connected with rectifier bridge, and output filter circuit is connected with output interface; Output interface is connected with voltage sampling circuit, and voltage sampling circuit is connected with 12C5A60S2 single-chip microcomputer; Show charactron by 12C5A60S2 Single-chip Controlling, for showing magnitude of voltage.
Described 12C5A60S2 single-chip microcomputer by key control, realizes different voltage adjustable by the control be connected with 12C5A60S2 single-chip microcomputer.
It is arbitrarily adjustable in the scope of 0-24V that portable adjustable voltage charger control system of the present invention can realize voltage, thus be various different electric power supplies.It is little that the charger utilizing this control system to make has volume, lightweight, and can carry with, output voltage stabilization, operating efficiency is high, and generate heat little, cost is low, and magnitude of voltage people is manually adjustable, and the advantage that magnitude of voltage can clearly show.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of portable adjustable voltage charger control system of the present invention.
