Description

A kind of soft start controller

Technical field

This utility model relates to a kind of controller, specifically a kind of soft start controller。

Background technology

In various past and existing frequently-used power supply, design mostly exists an intrinsic shortcoming: to draw a bigger electric current powering up moment, this electric current is likely to be breached 10 ~ 100 times of power supply static working current, thus has at least the problem that possibility produces two aspects, first, if current and power supply can not supply enough starting currents, power supply cannot start possibly into a kind of lock-out state, second, this electric current is likely to result in the reduction of input supply voltage, it is sufficient to cause other power-equipment instant power-downs using same input power。More existing soft start controllers are substantially the highest threshold values for input voltage and limit, and such as when input voltage exceedes how many scope, soft starting circuit just can start, and this mode is inoperative to some little disturbing pulse signals。

Utility model content

The purpose of this utility model is in that to provide a kind of soft start controller, with the problem solving to propose in above-mentioned background technology。

For achieving the above object, this utility model provides following technical scheme:

A kind of soft start controller, including not gate F1, not gate F2, resistance R1, resistance R2, electric capacity C1, LED and diode D1, described not gate F1 input connects ground capacity C2 and input Vi respectively, not gate F1 outfan connects resistance R1 and resistance R2 respectively, the resistance R2 other end connects diode D1 negative pole, diode D1 positive pole connects ground capacity C1, resistance R1 and not gate F2 input respectively, not gate F2 outfan connecting luminous diode LED positive pole, LED negative pole connects output end vo。

As this utility model further scheme: described diode D1 is counnter attack diode。

Compared with prior art, the beneficial effects of the utility model are: this utility model soft start controller, by the pulse width of input pulse is limited, effectively prevent the de-stabilising effect that circuit is caused by narrow pulse signal, circuit structure is simple, cost is low, and volume is little, is especially suitable for and promotes the use of。

Accompanying drawing explanation

Fig. 1 is the circuit diagram of soft start controller。

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, in this utility model embodiment, a kind of soft start controller, including not gate F1, not gate F2, resistance R1, resistance R2, electric capacity C1, LED and diode D1, described not gate F1 input connects ground capacity C2 and input Vi respectively, not gate F1 outfan connects resistance R1 and resistance R2 respectively, the resistance R2 other end connects diode D1 negative pole, diode D1 positive pole connects ground capacity C1, resistance R1 and not gate F2 input respectively, not gate F2 outfan connecting luminous diode LED positive pole, LED negative pole connects output end vo；Described diode D1 is counnter attack diode。

Operation principle of the present utility model is: refer to Fig. 1, this utility model only has the input pulse that pulsewidth (is determined) more than sometime by R1 and C1, could export at output end vo, in addition narrow disturbing pulse is all by circuit for eliminating, when exporting high level such as F1, charged by R1, C1, if the pulsewidth of input pulse is less than R1 and C1 charging interval (this time requires that on C1, voltage rises to F2 input threshold level), then it is inoperative to output, and D1 and R2 is discharge loop during F1 output low level；LED is display lamp, and electric capacity C2 plays the effect of first time absorption clutter in whole circuitry processes。

It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and when without departing substantially from spirit of the present utility model or basic feature, it is possible to realize this utility model in other specific forms。Therefore, no matter from which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes in the implication of the equivalency dropping on claim and scope included in this utility model。Any accompanying drawing labelling in claim should be considered as the claim that restriction is involved。

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。
