Abstract
The invention relates to a zero-standby power consumption non-polarized safety charger circuit in the field of battery chargers. The technical scheme is that: two shunt-wound normally open switches (K1-2 and K2-2) are connected to the input end of a transformer through a commercial power input end; one of polarity identification rectifier diodes (D1 and D2) is connected in series with each of polarity output ends M and N through each of the two output ends of the transformer; the polarities of the diodes (D1 and D2) are required to be kept consistent at the polarity output ends M and N; one of normally open switches (K1-1 and K2-1) is connected in parallel with the two ends of each of the diodes (D1 and D2); a moving contact of each of the normally open switches (K1-1 and K2-1) is connected with each of the polarity output ends M and N; the two ends of a coil of a relay J1 are connected between normally open contacts of the normally open switches (K1-1 and K2-1), and the two ends of a coil of a relay J2 are connected between normally closed contacts of the normally open switches (K2-1 and K1-1); the relays J1 and J2 control the turn-on/turn-off of the normally open switches (K1-1 and K1-2) and (K2-1 and K2-2) respectively; and therefore, an automatic polarity identification and conversion circuit is formed. The circuit is simple and convenient to manufacture; and a charger can accurately charge a battery without taking the polarity of the battery into account under the condition of short-circuit of the output ends.
Description
Technical field:
The present invention relates to the electrodeless safe charging device of the standby zero-power circuit in battery charge field.
Background technology:
Various on the market at present battery chargers are various in style, but all have a common characteristic, and charger is all established a mains switch, does not cut off the electricity supply, and charger is also in power consumption; During charging, just must press the correct polarity connection of battery and charge, and two output electrode joints can not short circuit, otherwise will burn charger or battery, but fire hazard is also made troubles to charging.
Summary of the invention:
The object of the invention is exactly the defective that exists to prior art.The electrodeless safe charging device of the standby zero-power circuit of a kind of automatic identification battery polar and short-circuit protection is provided.
Its technical scheme:
Be connected in series two parallelly connected normal open switch (K1-2, K2-2) to the transformer input by the mains electricity input end; Transformer output two ends are connected a polarity identification rectifier diode (D1, D2) respectively to polarity output M, N, and the polarity of diode (D1, D2) at polarity output terminal M, N is last will be consistent; Diode (D1, D2) two ends are a parallelly connected normal open switch (K1-1, K2-1) respectively; Moving contact (K1-1, K2-1) links to each other with polarity output terminal M, N respectively; Relay J 1, J2 coil two ends are connected on respectively between the normally-closed contact of (K1-1, K2-1) normally opened contact and (K2-1, K1-1); Relay J 1, J2 control (K1-1, K1-2), (K2-1, K2-2) switch respectively, constitute polarity identification and change-over circuit automatically.
Circuit structure of the present invention is simple, and is easy to use, need not consider the polarity of battery during use, chargings such as special interchangeable 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: be connected in series two parallelly connected normal open switch (K1-2, K2-2) to the transformer input by the mains electricity input end; Transformer output two ends are connected a polarity identification rectifier diode (D1, D2) respectively to polarity output M, N, and the polarity of diode (D1, D2) at polarity output terminal M, N is last will be consistent; Diode (D1, D2) two ends are a parallelly connected normal open switch (K1-1, K2-1) respectively; Moving contact (K1-1, K2-1) links to each other with polarity output terminal M, N respectively; Relay J 1, J2 coil two ends are connected on respectively between the normally-closed contact of (K1-1, K2-1) normally opened contact and (K2-1, K1-1); Relay J 1, J2 control (K1-1, K1-2), (K2-1, K2-2) switch respectively, constitute polarity identification and change-over circuit automatically.During charging, when M connects anode, N connects negative pole, electric current by M through D1, J1 coil to negative pole N, charging forms the loop, relay J 1 the electrician does, K1-1, K1-2 are closed, connect mains supply, M end output positive voltage, the N end is negative voltage, correctly charges for battery; When N connects anode, M connects negative pole, electric current by N through D2, J2 coil to negative pole M, charging forms the loop; Relay J 2 gets the electrician and does, and K2-1, K2-2 closure are connected mains supply, and the N end is exported positive voltage; The M end is negative voltage, correctly charges for battery, and realization polarity is discerned the purpose of conversion automatically; As M, when N does not have the battery of connecing, relay J 1, J2 do not have electricly, and K1-2, K2-2 are not closed, power supply no power, standby zero-power.
