Abstract
The utility model relates to a circuit for switching between a commercial power supply and a storage battery power supply, more specifically to a direct-current power supply ageing circuit taking storage batteries as intermediate bodies. The direct-current power supply ageing circuit is mainly composed of commercial power, AC/DC, a storage battery 1, DC/AC, a direct-current power supply, a storage battery 2, a charging circuit, and a master controller. The direct-current power supply is supplied with power by the storage battery 1 after the inversion of the DC/AC and supplies power to the storage battery 2. The master controller is connected with the storage battery 1 and the storage battery 2 through voltage detection modules. The direct-current power supply ageing circuit mainly recovers a large amount of electric energy; the direct-current power supply ageing circuit simultaneously conducts the ageing of the storage batteries in the processing of the ageing of the direct-current power supply; and the direct-current power supply ageing circuit employs the commercial power for complementary power supplying without influencing the normal ageing operation.
Description
Technical field
The utility model relates to a kind of storage battery power supply device field, field, particularly relates to the DC power supply aging circuit that a kind of storage battery is made intermediate.
Background technology
Burn-in chamber is the equipment that simulates a kind of high temperature, abominable test environment at high-performance electronic product (as: computer complete machine, display, terminating machine, auto electronic product, power supply unit, motherboard, monitor and switch type charger etc.), and this equipment has been widely used in fields such as power supply electronic, computer, communication, bio-pharmaceuticals.
The high low temperature ageing test of electronic product is to get rid of electronic product early failure, the necessary means of control product quality.The even property of temperature distributing disproportionation is the important technology index of burn-in chamber in the burn-in chamber, will directly influence the aging result who is placed on electronic product in the different burn-in chambers zone.At present, the electronic product burn-in chamber of domestic a lot of enterprises, the scope that its temperature control system detects only is certain some temperature in the burn-in chamber, thereby be difficult to solve the even practical problem of temperature distributing disproportionation in the burn-in chamber, thereby influenced the experimental result of the high low temperature ageing test of electronic product greatly.
The utility model content
At the problem that prior art exists, the purpose of this utility model provides the DC power supply aging circuit that a kind of storage battery is made intermediate.
The technical solution adopted in the utility model is: a kind of storage battery is made the DC power supply aging circuit of intermediate, mainly is made up of civil power, AC/DC, storage battery one, DC/AC, DC power supply, storage battery two, charging circuit, voltage detection module and master controller; Described master controller links to each other with charging circuit with AC/DC, and master controller also links to each other with storage battery two with storage battery one respectively by voltage detection module.
Described master controller is single-chip microcomputer, the charging circuit of described storage battery two to the charging circuit of storage battery one and civil power to storage battery one all with the master controller break-make.
Described DC power supply is its power supply after passing through the DC/AC inversion by storage battery one, and to storage battery two power supplies.
Described storage battery one is its charging by storage battery two, when the brownout of storage battery two, is its charging by civil power through AC/DC conversion back.。
Described master control detects the voltage of storage battery one and storage battery two in real time by voltage detection module.
The utility model compared with prior art has the following advantages:
1. the utility model is reasonable in design, simple in structure and the circuit part line is simple;
2. the utility model mainly is with regard to the power conservation in the DC power supply ageing process, mainly DC power supply is charged to storage battery two, storage battery two be DC power supply by storage battery one to storage battery one charging then, is its power supply by civil power during the interior undertension of described storage battery one; Mainly be to have reclaimed electric energy in a large number, and in the aging process of DC power supply, also carry out the aging of storage battery simultaneously.
