Abstract
The utility model relates to a simple constant current charger. The utility model is characterized in that a capacitance C1 is connected in series with the primary input end of a transformer B. The secondary output end of the transformer B is connected with the input ends of bridge rectifier circuits D1, D2, D3 and D4; the output ends of the bridge rectifier circuits D1, D2, D3 and D4 are connected with the C2 and the charge RL. The utility model has the advantages of simple circuit, low cost, small power consumption, etc.
Description
The utility model relates to the electric charger of a kind of simple and easy perseverance.
At present, adopt the transistor electronic circuit to reach the purpose of constant current usually, it needs right perseverance so effective, but circuit is complicated, the cost height.
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.
In order to achieve the above object, the utility model is achieved in that and is characterized in, is connected in series a capacitor C at the elementary input of transformer B
1The secondary output termination bridge rectifier D of transformer B
1-4Input, bridge rectifier D
1-4Output termination one 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.
The utility model compared with prior art has following advantage:
1, circuit is simple and easy, and cost is low;
2,,, become idle into meritorious so help improving electrical network effect factor because primary impedance is capacitive;
3, oneself power consumption is little, and long-term continuous operation is not generated heat, the reliability height, and security performance is good.
Fig. 1 is the utility model structural representation.
Below in conjunction with drawings and Examples the utility model is further described:
As shown in Figure 1, the elementary input at transformer B is connected in series a capacitor C
1After connect alternating current; The secondary output end of transformer B meets bridge rectifier D
1-4Input, bridge rectifier D
1-4Output termination one capacitor C
2And load R
