Abstract
The utility model discloses a simple CC (Constant Current) charger, wherein a capacitor C1 and a fuse are in series connection with the primary input end of a transformer B; the secondary output end of the transformer B is connected with the input end of a bridge-type rectifying circuit D1-4; and the output end of the bridge-type rectifying circuit D1-4 is connected with an electrolytic capacitor C2 and a load RL. The simple CC charger has simple circuit, low manufacturing cost, low consumption, high reliability, good safety, and smaller temperature change of the transformer during a long-term continuous work.
Description
Technical field
The utility model relates to a kind of charger, relates in particular to a kind of simple and easy constant current charger.
Background technology
At present, people adopt transistor electronic circuit or power module to add the purpose that accessory circuit reaches constant current usually, though this perseverance is so effective, circuit is comparatively complicated, and cost of manufacture is also higher.
The utility model content
It is simple that the purpose of this utility model provides a kind of circuit, the simple and easy constant current charger that cost is low.
To achieve these goals, the technical solution adopted in the utility model is: a kind of simple and easy constant current charger is connected in series a capacitor C at the elementary input of transformer B
1With a fuse; The secondary output termination bridge rectifier D of transformer B
1-4Input, bridge rectifier D
1-4Output termination one electrochemical capacitor C
2And load R
L, capacitor C
1Capacitive reactance should be greater than the induction reactance of the primary input terminal of transformer B, when the impedance at the secondary two ends of transformer B increased, the elementary impedance of transformer B also increased thereupon, because capacitor C
1Be certain value, the capacitive reactance of its input reduces, and primary current increases, and secondary voltage is increased; Otherwise primary current reduces, and secondary voltage reduces; Electrochemical capacitor C
2Be the filter capacitor after the rectification.
Compared with prior art, the utility model has the advantages that: this charger not only circuit is simple, and cost of manufacture is low, and power consumption is little, reliability is high, fail safe is good, and big variation does not take place the temperature of long-term continuous operation transformer yet.
