Abstract

The invention discloses a voltage stabilization device and electronic equipment. The voltage stabilization device includes: a positive voltage output unit, including a first comparison subunit and a first adjustment and current expansion subunit, wherein the first comparison subunit converts The received first positive voltage is corrected with the first reference voltage source voltage to output a first corrected positive voltage, and the first adjustment and current expansion sub-unit stabilizes and expands the received first corrected positive voltage. Stream processing, outputting a first stable positive voltage with a first ripple coefficient; a negative voltage output unit, including a second comparison subunit and a second adjustment current expansion subunit, wherein the second comparison subunit will receive the first A negative voltage is corrected with the ground voltage to output a first corrected negative voltage, the second adjustment current expansion sub-unit performs current expansion processing on the received first corrected negative voltage, and the output has the first ripple Coefficient of first stable negative voltage.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a voltage stabilizing device and electronic equipment. Background technique [0002] With the continuous development of science and technology, the types and quantities of electronic equipment are increasing day by day. In order to meet the high precision requirements of electronic equipment and prolong the service life of electronic equipment, it is urgent to use high stability and high precision regulated power supply for power supply. [0003] In the prior art, the stabilized power supply is mainly composed of two modules: a rectifier and transformer circuit and a filter and stabilizer circuit. First, the single-phase or three-phase AC voltage is changed by the transformer to a voltage value suitable for the rectification circuit, and then rectified and filtered. The circuit obtains a unipolar DC voltage, and finally obtains a stable voltage through the processing of the v...
