Abstract
The invention relates to a non-polarity charger circuit, and belongs to the field of battery charging. According to the technical proposal, a dual-polarity automatic identification circuit and a rectification polarity converting circuit are arranged between the output ends of a power transformer and two charging electrodes, wherein, two ends of a coil of a relay J1 are respectively connected to normally closed contacts (K2-1 and K2-2), movable contacts (K2-1 and K2-2) are respectively connected with a coil of a relay J2 in series, and a polarity identification diode D2 is connected with polarity output ends M and N (the anode of D2 is connected with N), thus the dual-polarity identification circuit is formed; and positive and negative voltage is output by the output ends of the transformer through a half-wave rectifier D1, the anode is connected with movable contacts (K1, K2-2), the cathode is connected with a normally closed contact K2-2 and a normally open contact K2-1, the movable contact K1 is connected with a pole M, and the relays J1 and J2 respectively control K1, K2-1 and K2-2 switches so as to form the rectification polarity converting circuit. The non-polarity charger circuit is especially applicable to charging a storage battery and the like.
Description
Technical field:
The present invention relates to the nonpolarity charger circuit in battery charge field.
Background technology:
The current battery charger is various in style, but all has a common feature, and just must connect, and the charger output can not short circuit, otherwise will burn battery or charger by correct battery polar, but fire hazard when serious.
Summary of the invention:
The object of the invention is exactly the defective that exists to prior art.The nonpolarity charger circuit of a kind of automatic identification polarity and short-circuit protection is provided.
Its technical scheme:: comprise bipolarity automatic identification circuit and rectification polarity switching between power transformer output and two charging electrodes.The bipolarity identification circuit is connect respectively on (K2-1, K2-2) normally-closed contact by relay J 1 coil two ends; (K2-1, K2-2) moving contact links to each other to polarity output M, N with relay J 2 coil tandem polarity identification diode D2 respectively; (the D2 positive pole links to each other with N), constitute polarity identification circuit; The rectification polarity switching is exported both positive and negative polarity by the transformer output through the D1 halfwave rectifier; Positive pole links to each other with moving contact (K1, K2-2); Negative pole links to each other with K2-2 normally-closed contact, K2-1 normally opened contact; The K1 moving contact extremely links to each other with M; Relay J 1, J2 control K1, (K2-1, K2-2) switch respectively, have formed polarity switching.
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.Chargings such as particularly suitable storage battery.
Description of drawings:
Accompanying drawing is the circuit theory diagrams of a kind of embodiment.IN is the civil power input among the figure; M, N are two charging electrode property outputs.
Embodiment:
Below in conjunction with accompanying drawing circuit formation and operation principle are further described:: comprise bipolarity automatic identification circuit and rectification polarity switching between power transformer output and two charging electrodes.The bipolarity identification circuit is connect respectively on (K2-1, K2-2) normally-closed contact by relay J 1 coil two ends; (K2-1, K2-2) moving contact links to each other to polarity output M, N with relay J 2 coil tandem polarity identification diode D2 respectively; (the D2 positive pole links to each other with N), constitute polarity identification circuit; The rectification polarity switching is exported both positive and negative polarity by the transformer output through the D1 halfwave rectifier; Positive pole links to each other with moving contact (K1, K2-2); Negative pole links to each other with K2-2 normally-closed contact, K2-1 normally opened contact; The K1 moving contact extremely links to each other with M; Relay J 1, J2 control K1, (K2-1, K2-2) switch respectively, have formed polarity switching.Energized, when M connect anode, when N connects negative pole, J1 gets the electrician and does, K1 is closed, M end output positive voltage, N end output negative voltage correctly charges to battery; When N connects anode, M connects negative pole, J2, J1 simultaneously the electrician does, when K2-1, K2-2 closed moment, normally closed point breaks off, J1 dead electricity and not working, K1 breaks off, N utmost point output positive voltage, M utmost point output negative voltage correctly charges to battery.Thereby realized no matter how battery polar inserts equal can correctly the charging to battery.M, when N does not have the battery of connecing, J1, J2 all do not work, and when M, N short circuit, can not damage charger yet.
