Description

A kind of direct current regulation circuit system

Technical field

This utility model is related to DC voltage-stabilizing technical field, more particularly to a kind of direct current regulation circuit system.

Background technology

With making rapid progress for electronic product, requirement of the various electronic products to DC source also more and more higher, low input DC voltage becomes main flow, therefore, DC voltage pressure drop conversion is essential.

DC decompression voltage stabilizing scheme is very more, and at present circuit types currently on the market can all produce high-frequency impulse, to whole Body circuit is needed in the more design of the aspect cost such as EMC, the type selecting of device, output filtering and cost.

Therefore, need a kind of new technical scheme to solve the above problems.

Utility model content

For the problem and shortage that above-mentioned prior art is present, the purpose of this utility model is to provide a kind of DC voltage-stabilizing electricity Road system.

To realize above-mentioned utility model purpose, the technical solution adopted in the utility model is a kind of direct current regulation circuit system System, including AC signal input socket, rectification chip, the control socket for controlling rectification chip start and stop, the first filter capacitor, Second filter capacitor, voltage stabilizing bridge and DC signal output socket, the signal output part of the AC signal input socket and rectification The input of chip is connected, and the outfan of the rectification chip is connected with the first filter capacitor, and first filter capacitor is passed sequentially through Voltage stabilizing bridge, the second filter capacitor by the input of DC signal output to DC signal output socket, the rectification chip it is defeated Going out end can be connected with some first filter capacitors, and be in parallel between first filter capacitor and the first filter capacitor, and one First filter capacitor correspondence one voltage stabilizing bridge, second filter capacitor and a DC signal output socket.

Used as further optimization of the present utility model, the input of AC signal input socket described in the utility model is believed Number for converter output AC signal.

Used as further optimization of the present utility model, the rated voltage of the first filter capacitor described in the utility model is more than The rated voltage of the second filter capacitor.

Compared to existing technology, its advantage is this utility model：This utility model circuit structure is simple, it is adaptable to enterprises Device is debugged, while this utility model adopts socket type structure, signal input and output are more convenient and safe, while right Rectification chip is externally provided with off control device so that whole circuit safety reliability is higher, without the need for the more cost of enterprise.
