The purpose of this utility model provides a kind of multi-functional dc charger, and it is a kind of improvement to " charging, voltage stabilizing, illumination multi-purpose device ".It both can also provide the power supply of the direct current of 1.5-15V as various household electrical appliance for dry battery charge, as outside the anxious illumination that should have a power failure, and also can also be motorcycle, the automobile storage battery charging.
The purpose of this utility model is achieved in that it comprises current stabilization circuit, power supply circuits, charging circuit, charging display circuit and power-cut emergency lighting circuit.
In the current stabilization circuit of rectifier bridge AC side, four electric capacity in parallel with bulb are arranged, each electric capacity and bulb all have a control switch of series connection with it, and each electric capacity also has the discharge resistance of a parallel connection.Utilize this circuit and rectifier bridge that the 60mA-8A direct current can be provided, if utilize halfwave rectifier that the 30mA-4A direct current can be provided, for motorcycle or automobile storage battery charging.
Power supply circuits are located between rectifier bridge and the battery pack to be charged, and this circuit has 10 groups of 21 rectifying tubes of serial connection, and every group of control corresponding switch and show the light-emitting diode of every group of rectifying tube operating state.21 rectifying tubes can be divided into ten groups by following scheme in the power supply circuits: first three rectifying tube is one group, and then per later on two rectifying tubes are one group.In this circuit, also have the short switch, external electric supply socket and the capacitor that are in parallel with the rectifying tube control switch.For the display voltage value, have one with 21 voltmeters that rectifying tube is in parallel.Alternating current utilizes power supply circuits that the direct current of 1.5-15V, 30mA-1.5A just can be provided, to satisfy the needs of various household electrical appliance after rectification.
Charging circuit is made up of the bulb in the current stabilization circuit or electric capacity and rectifier bridge, with bulb or capacitance partial pressure, after the rectification to batteries charging, charging current 0.05-2A, charging voltage is slightly larger than the battery pack residual voltage all the time, can reach 0-55V.
Power-cut emergency lighting electric routing battery group and bulb in parallel are with it formed, and utilize battery pack to be bulb powered.In this circuit, also have another short switch in parallel with battery pack, when providing power supply for household electrical appliance with this switch connection circuit.
The charging display circuit is that the switch, the light-emitting diode that are connected in series three rectifying tubes and a parallel connection with it on circuit between power-cut emergency lighting circuit external electric supply socket and the rectifier bridge are formed.Establish a switch at rectifier bridge, in order to realize all-wave or halfwave rectifier.
Good effect of the present utility model: the utility model can be batteries charging, do outside the power-cut emergency lighting, can utilize current stabilization circuit, rectifier bridge and power supply circuits to provide 1.5-15V, 30mA-8A direct current again, also can utilize current stabilization circuit to provide the 30mA-8A direct current to be motorcycle, automobile storage battery charging to satisfy various Household Appliance.
