Abstract
The utility model relates to an electron product aging detection device technical field, concretely relates to power module series connection aging device, include at least one power module, at least one unidirectional flux device and an electronic load of series connection in proper order, power module is two when above, keeps apart with the unidirectional flux device between every power module, the utility model discloses simple structure, the cost drops into for a short time, and occupation space is little, and it is short to occupy the power manufacturing plant time.
Description
Technical field
This utility model relates to electronic product degradation detecting device technical field, is specifically related to a kind of power module series connection aging equipment。
Background technology
High performance electronics is carried out aging for a long time by the test environment that power source aging refers under mal-conditions such as simulating a kind of high temperature, high low pressure sudden change, load characteristic variation, to improve the technological process of production of Product Safety, stability and reliability。Burn-in test is the inspection that must carry out before power supply product dispatches from the factory。Pass through burn-in test, it is possible to accelerate check valve power supply stability in client terminal use procedure。At present; power supply product senile experiment is usually and is concentrated in together by centrally connected power supply (exchange or direct current) by the product that many needs are aging; make it to protect constant high temperature in an environment closed simultaneously; and by the Power Recovery of electrical source consumption that energy-recuperation system will be aging; this equipment is referred to as burn-in chamber; because it be one close the space as house in, the power supply product being aging in a large number be individually positioned in the dividing plate of lattice one lattice carries out aging。
Power source aging is that all power supply factories holding time is the longest, and cost puts into maximum link。Current all of producer is all that each road power module adopts a cement resistor or electronic load to complete aging work。Although this way is simple, but needs to put into substantial amounts of cement resistor or electronic load, inherently causing huge waste, additionally different products also needs to different frocks, also needs to take very big place simultaneously。
Utility model content
The purpose of this utility model is in that to provide a kind of power module series connection aging equipment, and its simple in construction, cost puts into little, takes up room little, takies the power supply factory time short。
For achieving the above object, this utility model provides following technical scheme:
A kind of power module series connection aging equipment, including at least one power module being sequentially connected in series, at least one one way conducting device and an electronic load, when described power module is two or more, isolates with one way conducting device between each power module。
Further, described one way conducting device is diode or metal-oxide-semiconductor。
Further, the circuit that described power module, one way conducting device and electronic load are constituted is also associated with input voltage, the circuit that described input voltage is consisted of with power module, one way conducting device and electronic load linkage relay is connected, and described input voltage includes high voltage, rated voltage and low-voltage。
Compared with prior art, the beneficial effects of the utility model are: this utility model is in series with one way conducting device between each power module, so both allowed the electric current by each power module equal, it is possible to prevent again power module to be subject to backward voltage to be added to module and cause the damage of module, and this patent all has only to an electronic load for the power module of different model, so can be greatly saved cost and place that producer puts into, also allow for training and the operation of producers simultaneously。
Accompanying drawing explanation
Fig. 1 is the circuit diagram of a kind of power module series connection aging equipment of this utility model。
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments。Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection。
Refer to Fig. 1, a kind of power module series connection aging equipment, including at least one power module 1 being sequentially connected in series, at least one one way conducting device 2 and an electronic load 3, when described power module is two or more, isolate with one way conducting device between each power module。This utility model is in series with one way conducting device between each power module, so both allowed the electric current by each power module equal, it is possible to prevent again power module to be subject to backward voltage to be added to module and cause the damage of module, and this patent all has only to an electronic load for the power module of different model, so can be greatly saved cost and place that producer puts into, also allow for training and the operation of producers simultaneously。
As this utility model specific embodiment, described one way conducting device is diode or metal-oxide-semiconductor。The circuit that described power module, one way conducting device and electronic load are constituted is also associated with input voltage, the circuit that described input voltage is consisted of with power module, one way conducting device and electronic load linkage relay 4 is connected, and described input voltage includes high voltage 5, rated voltage 6 and low-voltage 7。Linkage relay in this patent is for controlling the energising of power module and the off-position that are aging, and the outfan of the power module being aging is connected with input voltage by linkage relay；Input voltage includes high voltage, rated voltage and low-voltage, and described high voltage is 260V, and rated voltage is 220V, and low-voltage is 180V。In addition, it is to be understood that, although this specification is been described by according to embodiment, but not each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, description should be made as a whole by those skilled in the art, and the technical scheme in each embodiment through appropriately combined, can also form other embodiments that it will be appreciated by those skilled in the art that。
