Abstract
The invention relates to a random battery polarity access charger circuit. A polarity identification circuit, a power switch circuit and a polarity conversion circuit are arranged between an output end of a power transformer and two electrodes of an output. The polarity identification circuit is formed in a mode that a polarity identification diode D1 is connected in series with a coil of a relay J1 and a coil of a relay J2 is connected in parallel to both ends M and N of the output; the power switch circuit is formed by a K2 normally-open switch connected in series between one end of an output of the transformer and the end N of the polarity output; and the polarity conversion circuit is formed in a mode that the other end of the output of the transformer is connected with a cathode of a diode D2 and an anode of a diode D3, a movable contact of a switch K1 is connected with the M electrode, a normally-closed contact and a normally-open contact of the switch K1 are respectively connected with an anode of the diode D2 and a cathode of the diode D3, and the switch K1 is controlled by the relay J1. Due to the adoption of the random battery polarity access charger circuit, not only is a charger protected under the condition of short circuit of the output end, but also the access of random polarity can realize correct charging of a battery. The random battery polarity access charger circuit is particularly suitable for charging a storage battery and the like.
Description
Technical field:
The battery polar that the present invention relates to the battery charger field at will connects charger circuit.
Background technology:
The current battery charger is various in style, but all has a common characteristic, and the correct polarity that just must connect battery connects, and the charger output can not short circuit, otherwise will burn battery or charger, but fire hazard seriously the time.
Summary of the invention:
The object of the invention is exactly the defective that exists to prior art, provides the battery polar of a kind of automatic identification polarity and short-circuit protection at will to connect charger circuit.
Its technical scheme: between power transformer output and output two electrodes, comprise a polarity identification circuit, power switch circuit and polarity switching.Polarity identification circuit by diode D1 SRE J1 coil and relay J 2 coils from parallel connection of coils to export M, the N two ends constitute; Power switch circuit is exported the K2 normal open switch that an end and polarity exports between the end N and is constituted by being serially connected in transformer; Polarity switching is anodal by transformer output another termination D2 negative pole and D3, and the K1 moving contact extremely links to each other with M, and the normally-closed contact of K1, normally opened contact are anodal with D2 respectively, the D3 negative pole links to each other, and J1 relay control K1 switch constitutes polarity switching.
This circuit structure is simple, and is easy to use.Not only protect charger under the situation of output short circuit, and the polarity access all can realize battery is correctly charged arbitrarily.
Description of drawings:
Accompanying drawing is the circuit theory diagrams of a kind of embodiment.IN is the civil power input among the figure, and M, N are two charging polarity outputs.
Embodiment:
Below in conjunction with accompanying drawing circuit formation and operation principle are further described: its technical characterictic is: between power transformer output and output two electrodes, comprise a polarity identification circuit, power switch circuit and polarity switching.Polarity identification circuit by diode D1 SRE J1 coil and relay J 2 coils from parallel connection of coils to export M, the N two ends constitute; Power switch circuit is exported the K2 normal open switch that an end and polarity exports between the end N and is constituted by being serially connected in transformer; Polarity switching is anodal by transformer output another termination D2 negative pole and D3, and the K1 moving contact extremely links to each other with M, and the normally-closed contact of K1, normally opened contact are anodal with D2 respectively, the D3 negative pole links to each other, and J1 relay control K1 switch constitutes polarity switching.During charging, when M connects anode, N connects negative pole, J1, J2 simultaneously the electrician does, K1, K2 are closed, M exports positive voltage, N is a negative voltage, and battery is correctly charged.When N connects anode, M connects negative pole, and J2 gets electric, and K2 is closed, and J1 oppositely ends work because of D1, and N exports positive voltage, and M is negative voltage, battery is correctly charged.Realized that polarity discerns the purpose of convert charging automatically, as M, when N does not have the battery of connecing, J1, J2 all do not have electricly, and M, N with regard to no-voltage output, can not damage charger during short circuit yet yet.
