Abstract
The invention relates to a non-polar safe charger circuit in the battery charging circuit field. The technical scheme includes that a bipolarity identification circuit and a rectifying and converting circuit are arranged between output ends of a transformer and two charging electrodes. One end of a coil of each of a relay J1 and a relay J2 of the bipolarity identification circuit is connected with one output end of the transformer and a polarity output end N, the other ends of the J1 coil and the J2 coil are serially connected with a polarity rectifier diode D2 and a polarity rectifier diode D1 through a K2 normally-closed contact and a K1 normally-closed contact respectively, the anode of the D2 and the cathode of the D1 are connected with a polarity output end M respectively, the other output end of the transformer is connected with the K1 normally-closed contact and the K2 normally-closed contact, and the relay J1 and the relay J2 control the switch K1 and the switch K2 respectively to form a bipolarity identification and conversion circuit. The non-polar safe charger circuit is simple in structure and convenient in manufacturing, a charger can be protected during short circuit of output ends, any pole of batteries can be switched in for correctly charging the batteries, and the non-polar safe charger circuit is especially applicable to charging of storage batteries and the like.
Description
Technical field:
The present invention relates to the electrodeless safe charging device circuit in battery charger field.
Background technology:
Battery charger is various in style in the market, be connected with the correct polarity of power supply but all must press battery, and polarity output terminal can not short circuit, otherwise will burn battery or charger, even cause fire.
Summary of the invention:
The object of the invention is exactly the defective that exists to prior art, and a kind of electrodeless safe charging device circuit of automatic identification battery polar is provided.
Its technical scheme is: comprise bipolarity identification circuit and rectification change-over circuit between transformer output and two charging electrodes.Bipolarity identification change-over circuit by relay J 1, J2 coil one end exports an end with transformer and polarity output terminal N links to each other; The other end of J1, J2 coil is connected in series with polarity rectifier diode D2, D1 through the normally-closed contact of K2, K1 respectively; The positive pole of D2 links to each other with polarity output terminal M respectively with the D1 negative pole; The transformer output other end links to each other with the normally opened contact of K1, K2, and relay J 1, J2 control K1, K2 switch respectively, constitutes bipolarity identification change-over circuit.
This circuit structure is simple, and is easy to use.Not only under the situation of output short circuit, protect charger, and the polarity access can correctly be charged all arbitrarily to battery.
Description of drawings:
Accompanying drawing is a kind of embodiment circuit theory diagrams.IN is the civil power input among the figure, and M, N are the outputs of two charging polarities.
Embodiment:
Further describe with regard to its circuit formation and operation principle below in conjunction with accompanying drawing: transformer output two ends connect (K1, K2) normally opened contact and polarity output stage N respectively; Diode D1 positive pole and D2 negative pole are formed bipolarity and are discerned change-over circuit automatically respectively through K1, K2 normally-closed contact and relay J 2, J1 coil tandem and M, N polarity output terminal.During charging, when M connects anode, N connects negative pole, electric current is through anodal M → D2 → normally-closed contact K2 → J1 relay coil → N negative pole, and J1 gets the electrician and does, and K1 is closed, and the reverse J2 of the D1 K1 normally-closed contact of not working breaks off the J2 relay coil.M utmost point output positive voltage correctly charges to battery; Connect negative pole when N meets anode M, electric current is through anodal N → J2 coil → K1 normally-closed contact → D1 → M negative pole, and J2 gets the electrician and does; K2 is closed, and D2 is reverse, and J2 does not work; The K2 normally-closed contact breaks off the J2 relay coil, and M output negative voltage N is positive voltage very, the charging operate as normal; The realization battery polar is discerned the purpose of conversion automatically.When not connecing battery, J1, J2 charging and by work, thereby M, N charging back output can not damage charger during short circuit yet.
