Description
technical field:
The utility model relates to a kind of series connection farad capacitive balance charger, belongs to security appliance field.
background technology:
Current, farad capacitor because of its life-span long, charging safety, capacity is large, day by day paid attention to, but, farad capacitor because of in its production process, the many factors such as uniformity and service condition, need high voltage, when using multiple series connection, there will be and partially fill phenomenon, and cause there is potential safety hazard.
summary of the invention:
The utility model relates to a kind of series connection farad capacitive balance charger, to realize the object to series connection farad capacitive safety equilibrium charging.
For realizing above-mentioned object, the utility model adopts following technical scheme:
A kind of series connection farad capacitive balance charger, comprises:
Balance resistance (1), farad capacitor (2), power input terminal (3), power output terminal (4), master fill diode (5), balance and fill diode (6), power supply ground (7); As shown in Figure 1.
Below in conjunction with accompanying drawing, technical construction of the present utility model and method are described: farad capacitor (2) is standard series connected, corresponding balance resistance (1) is also series connection, power input terminal (3) is connected with the top resistance of balance resistance (1), power input terminal (3) fills diode (5) by master and is connected with the top of farad capacitor (2), balance resistance (1) bottom with farad capacitor (2) bottom with power supply (7) be connected, the corresponding ohmically voltage of balance resistance (1), fill diode (6) by balance to be connected with farad capacitor (2), power output terminal (4) is connected with the output on farad capacitor (2) top, when power input terminal (3) has electric current to input, principal current is filled diode (5) by master and is charged to farad capacitor (2), at this moment, balance resistance (1) is by series resistance dividing potential drop, export a corresponding balanced voltage to corresponding farad capacitor (2), realize safe charging, when power input terminal (3) does not have an electric current, due to the one-way conduction effect of diode, farad capacitor (2) can not pass through balance resistance (1) electric discharge, save electric energy, improve power utilization efficiency.
The beneficial effects of the utility model: charge protection effect, can realize equilibrium charging to farad capacitor.
accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model.
detailed description of the invention:
In order to make the technical solution of the utility model clearly understand, below in conjunction with drawings and Examples, further describe the utility model, instantiation described herein, only in order to explain the utility model, is not limited to the utility model.
embodiment:
Refer to shown in accompanying drawing 1, farad capacitor (2) is standard series connected, corresponding balance resistance (1) is also series connection, power input terminal (3) is connected with the top resistance of balance resistance (1), power input terminal (3) fills diode (5) by master and is connected with the top of farad capacitor (2), balance resistance (1) bottom with farad capacitor (2) bottom with power supply (7) be connected, the corresponding ohmically voltage of balance resistance (1), fill diode (6) by balance to be connected with farad capacitor (2), power output terminal (4) is connected with the output on farad capacitor (2) top, when power input terminal (3) has electric current to input, principal current is filled diode (5) by master and is charged to farad capacitor (2), at this moment, balance resistance (1) is by series resistance dividing potential drop, export a corresponding balanced voltage to corresponding farad capacitor (2), realize safe charging.
