Abstract
The utility model relates to a power supply, concretely speaking is a redundancy power supply with the AC and DC in a mutual prepared manner, whose structure comprises a back plate, and the back plate is connected with the AC module and the DC module through the interface. Compared with the prior art, the utility model is a redundancy power supply with the AC and DC in a mutual prepared manner. The utility model is characterized in that: the utility model is of a proper design, simple structure, and low manufacturing cost and safe and reliable use with flexible expanding property.
Description
Technical field
The utility model relates to a kind of power supply, specifically provides a kind of alternating current-direct current to be equipped with the formula redundant power mutually.
Background technology
Power supply under the prior art only is connected to a kind of electric current input, is generally AC power and supplies with, if this design runs into power failure, will cause system to work as machine, may cause immeasurable loss to the user especially user of field of telecommunications.
Summary of the invention
The utility model is at above deficiency, provide a kind of reasonable in design, simple in structure, cost of manufacture is low, alternating current-direct current safe and reliable and that have a flexible extendibility is equipped with the formula redundant power mutually.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of alternating current-direct current is equipped with the formula redundant power mutually, comprises backboard, is connected with interchange module and direct current module by general-purpose interface on the backboard, and described general-purpose interface can connect interchange module or direct current module.
The direct current module comprises EMI filter circuit, high-frequency switch circuit and the output rectifier and filter of serial connection, and described high-frequency switch circuit and output rectifier and filter two ends are also and be connected to pwm control circuit.
Exchange EMI filter circuit, input rectifying filter circuit, high-frequency switch circuit and output rectifier and filter that module comprises serial connection, described high-frequency switch circuit and output rectifier and filter two ends are also and be connected to pwm control circuit.
Alternating current-direct current of the present utility model is equipped with the formula redundant power mutually and allows slotting (220VAC) interchange module and (48VDC) direct current module simultaneously, when being applied in fields such as telecommunications, its largest benefit is exactly: even alternating current breaks down, direct current module (as adopting powered battery) is still in work, can not cause system to work as machine, thereby ensure the reliability service of important service.
Meanwhile, alternating current-direct current of the present utility model is equipped with the formula redundant power has mutually also increased flexibility for the user, promptly have good extendibility, the user can select different power module (all adopt to exchange module or all adopt the direct current module, perhaps both use with) according to actual conditions.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural principle block diagram that a kind of alternating current-direct current is equipped with the formula redundant power mutually.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
Provide a most preferred embodiment below:
A kind of alternating current-direct current is equipped with the formula redundant power mutually, comprises backboard, is connected with interchange module and direct current module by general-purpose interface on the backboard, and described general-purpose interface can connect interchange module or direct current module.
The direct current module comprises EMI filter circuit, high-frequency switch circuit and the output rectifier and filter of serial connection, and described high-frequency switch circuit and output rectifier and filter two ends are also and be connected to pwm control circuit.
Exchange EMI filter circuit, input rectifying filter circuit, high-frequency switch circuit and output rectifier and filter that module comprises serial connection, described high-frequency switch circuit and output rectifier and filter two ends are also and be connected to pwm control circuit.
Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection range of the present utility model.
