Description
Technical field
The present invention relates to a kind of battery charger.
Background technology
Most of in the market battery charger circuit are single, generally do a Switching Power Supply, and constant current and constant voltage function are arranged, and batteries is charged.
But many outlying districts or mountain area are arranged, and the power fluctuation scope is big, and is just very high near the line voltage of power transformer, just very low away from the line voltage of transformer, causes the damage of charger easily, also causes storage battery to be not fully filled easily simultaneously.Sometimes to improve output voltage and can't realize especially in order to reach charging effect.
Fig. 1 is the theory diagram of existing battery charger; In order to satisfy the control requirement, general 48V charge in batteries voltage will reach about 59V at least, in order to reach good charging effect; The charger output voltage will arrive about 78V sometimes, common charger, and (common charger scheme) is shown in the following figure; Can't reach especially, because the fluctuation power supply of charger is very inconvenient for its control circuit; The fan power of its heat radiation also is difficult to voltage stabilizing to 12V, causes blower fan to descend useful life.The accessory power supply of AC side driving simultaneously also can cause the unsteadiness of control because of the fluctuation of output voltage and the fluctuation of electrical network, causes the easy aircraft bombing of main power source power tube.
Summary of the invention
Relatively poor for the voltage ripple of power network poor-performing, the reliability that overcome existing battery charger, as to have big potential safety hazard deficiency, the present invention provides a kind of battery charger that improves voltage ripple of power network performance, lifting reliability, reduces potential safety hazard.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of battery charger; Comprise rectification circuit, primary power switch device, main inverse changing driving circuit, main transformer, charging main power source and control and fan power; Said rectification circuit is connected with primary power switch device; Said main inverse changing driving circuit is connected with primary power switch device, and said primary power switch device is connected with the primary side of main transformer, and the secondary side of said main transformer is connected with said charging main power source; Said control is connected with said main inverse changing driving circuit with fan power; Said charger comprises that also said rectification circuit is connected from device for power switching with said from device for power switching, from inverse changing driving circuit and control transformer, and said device for power switching is connected from inverse changing driving circuit with said; Saidly be connected with the primary side of control transformer from inverse changing driving circuit; The secondary side of said control transformer is connected with fan power with control, the primary side of said control transformer be connected from inverse changing driving circuit, main inverse changing driving circuit, said control is connected from inverse changing driving circuit with said with fan power.
Technical conceive of the present invention is: in order to overcome the technical disadvantages that prior art exists, reach the stable of major loop AC side control, it is stable to reach DC side control power supply; Battery consumption electric energy not separates control and fan power, with two-way switch power source design (like Fig. 2) with the main power source that charges again; One road power is accomplished 3-5W; Because blower fan is little with the power of control electrical source consumption, about general 1-2W, so use the Switching Power Supply of two groups of common chargers.Because major loop control accessory power supply has had on the P cock power supply; So main power source no longer need be controlled those two windings with blower fan, these two windings are directly accomplished on the small-power switching power-supply, so only increase a small transformers on the hardware; Also only increase self accessory power supply winding of a high pressure winding and a P cock power supply; Like this because the power of P cock power supply is little, can accomplishing to exchange input range, very greatly also to guarantee to control power supply normal, and adding the P cock power supply is that internal control is used; Variable power is little, so output voltage stabilization.Especially " the major loop control accessory power supply " of main power source stable, the reliability of main circuit power pipe is strengthened greatly.
Simultaneously the transformer of main power source has had only two windings (common want 4 windings), and technology is simple, the total cost increase seldom, but reliability, fail safe, voltage ripple of power network performance all improve a lot, can satisfy the large tracts of land of this series products and promote and application.
Beneficial effect of the present invention mainly shows: improve the voltage ripple of power network performance, promote reliability, reduce potential safety hazard.

Embodiment
Below in conjunction with accompanying drawing the present invention is further described.
With reference to Fig. 2; A kind of battery charger; Comprise rectification circuit, primary power switch device, main inverse changing driving circuit, main transformer, charging main power source and control and fan power, said rectification circuit is connected with primary power switch device, and said main inverse changing driving circuit is connected with primary power switch device; Said primary power switch device is connected with the primary side of main transformer; The secondary side of said main transformer is connected with said charging main power source, and said control is connected with said main inverse changing driving circuit with fan power, and said charger also comprises from device for power switching, from inverse changing driving circuit and control transformer; Said rectification circuit is connected from device for power switching with said; Said device for power switching is connected from inverse changing driving circuit with said, saidly is connected with the primary side of control transformer from inverse changing driving circuit, and the secondary side of said control transformer is connected with fan power with control; The primary side of said control transformer be connected from inverse changing driving circuit, main inverse changing driving circuit, said control is connected from inverse changing driving circuit with said with fan power.
In the present embodiment, separate control and fan power with the charging main power source, with two-way switch power source design (like Fig. 2); One road power is accomplished 3-5W; Because blower fan is little with the power of control electrical source consumption, about general 1-2W, so use the Switching Power Supply of two groups of common chargers.Because major loop control accessory power supply has had on the P cock power supply; So main power source no longer need be controlled those two windings with blower fan, these two windings are directly accomplished on the small-power switching power-supply, so only increase a small transformers on the hardware; Also only increase self accessory power supply winding of a high pressure winding and a P cock power supply; Like this because the power of P cock power supply is little, can accomplishing to exchange input range, very greatly also to guarantee to control power supply normal, and adding the P cock power supply is that internal control is used; Variable power is little, so output voltage stabilization.Especially " the major loop control accessory power supply " of main power source stable, the reliability of main circuit power pipe is strengthened greatly.
Simultaneously the transformer of main power source has had only two windings (common want 4 windings), and technology is simple, the total cost increase seldom, but reliability, fail safe, voltage ripple of power network performance all improve a lot, can satisfy the large tracts of land of this series products and promote and application.
