Abstract
The utility model discloses a capacitive constant-current charger, which comprises a bridge rectifier, a capacitor C, a power supply indicating lamp (3), a power supply switch (2) and an outer shell (1). The capacitive constant-current charger is a charging device without transformers. Because the capacitor is adopted, the capacitive constant-current charger has the characteristics of constant current charge, simple structure, good charging performance, low manufacturing cost, etc. The electric capacity of the capacitor C is designed to be adjustable for adapting to charge for various specifications of accumulators, having large adaptable ranges.
Description
The utility model relates to a kind of device to charge in batteries.
The existing charger that generally uses, owing to adopted transformer, its weight is big, cost is high, electric energy loss and make big with raw materials consumption.The charger line construction complexity that also has is difficult to extensive use.
The purpose of this utility model is, designs a kind of condenser type constant current charger, makes it have characteristics simple in structure, that charging effect good, electric energy loss is little and cost is low.
Below in conjunction with accompanying drawing the utility model is explained.
Fig. 1 is an external structure of the present utility model, and it has shell (1) and mains switch (2), power supply indicator (3), ac power input end (5) and charging output (4).Fig. 2 is a circuit structure of the present utility model, and it comprises one by crystal diode D
1To D
4The bridge rectifier that constitutes, this rectifier has output (4), and it is connected to charging accumulator.Capacitor C
1An end and an ac input end of described bridge rectifier joins and its other end is connected on an end of AC power (5), and the other end of another ac input end of described bridge rectifier and AC power (5) joins.At described interchange input side, also be connected to XD indicator light (3) and mains switch K(2) and fusing insurance BX.Also can connect voltmeter and ammeter at described output (4), with indication charging voltage and electric current.
In circuit structure shown in Figure 2, if with described capacitor C
1Capacitance be designed to adjustablely, then enlarged its scope of application, can be to the charge in batteries of plurality of specifications.Fig. 3 has pointed out to make described capacitor C
1Become adjustable a kind of practical structures, promptly a multipole multidigit change over switch KB is successively respectively with capacitor C

6In place in circuit, the capacitance in the described circuit is changed.
Operation principle of the present utility model is that when AC power was in certain half cycle, this power supply was both to charge in batteries, again to capacitor C
1Charging; And when power supply was in another half cycle, power supply was to charge in batteries, and the capacitor discharge also adds to storage battery, formed stack, produced the pulsation charging current, realized charge function.Its operating current is less than exchanging input current.Owing to saved traditional transformer, reduced the electric energy loss that brings owing to transformer, and its cost reduced greatly.In case capacitor C
1Capacitance determine that charging current is exactly constant, does not need to install voltage stabilizing, constant-current stabilizer, need be in load circuit yet installation insurance (capacitor make load short circuits harmless), structure is simplified greatly.Described capacitor C
1Capacitance big more, then Shu Chu charging current is big more.
Embodiment: when storage battery be 14V, 10AH, when AC power is 220V, capacitor C
1Be the parallel connection of 9 1.2 μ F capacitors, D
1To D
4Be 1N4007, this moment, the loaded work piece electric current was 0.6A.
From the above, the utlity model has simple in structure, cost is low, charging performance good, power saving, raw material economize and the big characteristics of the scope of application.
Description of drawings: Fig. 1 is an external structure, and Fig. 2 and Fig. 3 are actual circuit structure, wherein:
1---shell
2---mains switch
3---power supply indicator
4---the charging output
5---ac power input end
Claims (2)
1, a kind of condenser type constant current charger comprises that shell (1), mains switch (2), power supply indicator (3), ac power input end (5) and charging output (4), its circuit structure comprise one by crystal diode D
1To D
4The bridge rectifier that constitutes, mains switch (2), power supply indicator (3) are connected on fusing insurance BX and exchange input side, and feature of the present utility model is capacitor C
1An end and an ac input end of described bridge rectifier joins and its other end is connected on an end of AC power (5), the other end of another ac input end of described bridge rectifier and AC power (5) joins.
2, condenser type constant current charger according to claim 1 is characterized in that, described capacitor C
1Capacitance be adjustable.
