The circuit is characterized in that a polarity identification commutation circuit and a power output switch circuit are arranged between the output end of a power transformer and two charging electrodes, wherein a coil of a relay J2 is connected between polarity output ends M and N and controls a normally open switch K2 connected between the output end of the transformer and a polarity identification circuit, thus forming the power switch circuit; a coil of a relay J1 is connected with a diode D1 between the ends M and N in series and the anode of D1 is connected with N, thus forming a polarity identification switching circuit; and the anode of a diode D2 is connected with a normally closed contact K1-1 and a normally open contact K1-2 respectively, the cathode of D2 is connected with a normally closed contact K1-2 and a normally open contact K1-1 respectively, movable contacts K1-1 and K1-2 are connected at the output end of the transformer and the polarity output end M respectively, and the relay J1 is used for controlling switches K1-1 and K1-2, thus forming a polarity switching circuit. The circuit has a simple structure, is convenient to use, not only can effectively protect chargers under the condition of short circuit at the output end but also can correctly charge the batteries under the condition of any polarity connection.
Description
Technical field:
The present invention relates to the electrodeless safe charging device circuit in battery charger field.
Background technology:
Various on the market at present battery chargers are various in style, but all have a common characteristic, and just must press the correct polarity connection of battery and charge, and two output electrodes can not short circuit, otherwise will burn charger or battery, but fire hazard also.
Summary of the invention:
The object of the invention is exactly the defective that exists to prior art.The electrodeless safe charging device circuit of a kind of automatic identification battery polar and short-circuit protection is provided.
Its technical scheme:
Comprise a polarity identification rectification change-over circuit and switch of power supply output circuit between power transformer output and two charging electrodes.This switching circuit is connected between polarity output terminal M, the N by relay J 2 coils, and control is connected on transformer and exports the K2 normal open switch between an end and the polarity identification circuit, constitutes power switch circuit; In M, N two ends, the D1 positive pole links to each other with N the polarity identification change-over circuit by relay J 1 coil series diode D1; The rectification change-over circuit is connected the normally opened contact of K1-1 normally-closed contact and K1-2 respectively by the positive pole of diode D2; The D2 negative pole connects the normally opened contact of normally-closed contact K1-2 and K1-1 respectively; The moving contact of K1-1, K1-2 is connected on transformer output upper end and the polarity output terminal M; Relay J 1 is used to control K-1, K1-2 change over switch, constitutes polarity switching.
Circuit of the present invention is simple, and is easy to use, need not consider the polarity of battery during use, is particularly suitable for chargings such as 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 polarity outputs.
Embodiment:
Below in conjunction with accompanying drawing circuit formation and operation principle are further described: comprise a polarity identification rectification change-over circuit and switch of power supply output circuit between power transformer output and two charging electrodes.This switching circuit is connected between polarity output terminal M, the N by relay J 2 coils, and control is connected on transformer and exports the K2 normal open switch formation power switch circuit between an end and the polarity identification circuit; In M, N two ends, the D1 positive pole links to each other with N the polarity identification change-over circuit by relay J 1 coil series diode D1; The rectification change-over circuit is connected the normally opened contact of K1-1 normally-closed contact and K1-2 respectively by the positive pole of diode D2; The D2 negative pole connects the normally opened contact of normally-closed contact K1-2 and K1-1 respectively; The moving contact of K1-1, K1-2 is connected on transformer output upper end and the polarity output terminal M; Relay J 1 is used to control K-1, K1-2 change over switch, constitutes polarity switching.During charging, when M termination anode, when N connect negative pole, relay J 2 got the electrician and does, and K2 is closed, and charging forms the loop, and M holds the output positive voltage, and N is a negative voltage, correctly charges to battery, and relay J 1 is oppositely ended work because of D1; When N connects anode, M connect negative pole J1, J2 simultaneously the electrician does, K2, K1-1, K1-2 are closed simultaneously.K1-1, K1-2 normally-closed contact break off, and normally opened contact is closed, N utmost point output positive voltage, and M is a negative voltage, correctly charges to battery, realizes the polarity purpose of conversion automatically; As M, when N does not have the battery of connecing, J2 does not have electricly, and K2 is not closed, and circuit does not have the loop and forms, and can not damage charger during short circuit yet.
