Description
Technical field
The utility model relates to a kind of voltage stabilizing circuit.
Background technology
At present, the power supply that market occurs is adopt the series connection of multiple voltage stabilizing didoe to the protection exporting transient voltage mostly, but, the shortcoming of this kind of method is: when a voltage stabilizing didoe damage or when there is other problems cisco unity malfunction, then the whole voltage-stabilizing system be made up of multiple voltage stabilizing didoe can not reach good pressure stabilization function, the damage probability of power supply output loading increases, and safety issue can not ensure.
Utility model content
In view of the above-mentioned problems in the prior art, main purpose of the present utility model is to address the deficiencies of the prior art, the utility model provides a kind of safe and reliable voltage stabilizing circuit, and this voltage stabilizing circuit can reach the effect of voltage stabilizing at short notice, with prevent to load voltage produce impact.
The utility model provides a kind of voltage stabilizing circuit, comprise voltage input end and voltage output end, multiple transient voltage suppressor diode in parallel between described voltage input end and voltage output end, described multiple transient voltage suppressor diode is one or more transient voltage suppressor diodes.
Optionally, a transient voltage suppressor diode in parallel between described voltage input end and described voltage output end.
Optionally, three transient voltage suppressor diodes in parallel between described voltage input end and described voltage output end.
The utility model has the following advantages and beneficial effect: the utility model improves a kind of voltage stabilizing circuit, this voltage stabilizing circuit comprises voltage input end and voltage output end, multiple transient voltage suppressor diode in parallel between described voltage input end and voltage output end, described multiple transient voltage suppressor diode is one or more transient voltage suppressor diodes, such as, when Switching Power Supply exports 68V voltage, at an output transient voltage suppressor diode P6KE75CA in parallel, output voltage can be stabilized between 71.3 ~ 78.8V in very short time, avoid the too high impact caused load of output voltage, improve stability and the fail safe of system.
Accompanying drawing explanation
Fig. 1 is the structural representation of voltage stabilizing circuit of the present utility model;
Fig. 2 is the another kind of structural representation of voltage stabilizing circuit of the present utility model.
Embodiment
With specific embodiment, the utility model is further described below with reference to accompanying drawings.
As depicted in figs. 1 and 2: a kind of voltage stabilizing circuit of the utility model embodiment, comprise voltage input end and voltage output end, multiple transient voltage suppressor diode in parallel between described voltage input end and voltage output end, described multiple transient voltage suppressor diode is one or more transient voltage suppressor diodes, such as, when Switching Power Supply exports 68V voltage, at an output transient voltage suppressor diode P6KE75CA in parallel, output voltage can be stabilized between 71.3 ~ 78.8V in very short time, avoid the too high impact caused load of output voltage, improve stability and the fail safe of system.
As the preferred implementation of above-described embodiment, a transient voltage suppressor diode in parallel between described voltage input end and described voltage output end, as shown in Figure 1.
As the preferred implementation of above-described embodiment, three transient voltage suppressor diodes in parallel between described voltage input end and described voltage output end, as shown in Figure 2, when one of them transient voltage suppressor diode damages, do not affect the use of other transient voltage suppressor diodes, whole voltage stabilizing didoe voltage-stabilizing system can reach voltage regulation result.
Last it is noted that above-described each embodiment is only for illustration of the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in previous embodiment, or to wherein partly or entirely technical characteristic carry out equivalent replacement; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment technical scheme of the utility model.
