Abstract

The invention discloses a voltage stabilizing device for supplying power in a wide voltage range, comprising: a voltage conversion module, which has a boost mode and a buck mode, and controls the output voltage through a PWM signal; a detection module, which detects the input voltage and the output voltage of the voltage conversion module Voltage: The main control module switches the boost mode or the buck mode according to the target voltage and the input voltage, and then adjusts the duty cycle of the PWM signal according to the target voltage and the output voltage, so that the output voltage meets the target voltage. The voltage conversion module of the present invention has a boost mode and a step-down mode, switches between different working modes according to the input voltage and the target voltage, and then adjusts the PWM signal to adapt to the power supply of a wider range of voltages.

Description

technical field [0001] The invention relates to the technical field of power supply circuits, in particular to a voltage stabilizing device for power supply in a wide voltage range. Background technique [0002] With the rapid development of electrical equipment, there are more and more types of electrical equipment, and there are more and more power supply voltage standards. In order to meet different power supply requirements, the equipment must meet a wider supply voltage. The voltage stabilizing device in the prior art usually adopts a single-mode voltage conversion module to adjust its output voltage only by adjusting the duty ratio of the PWM signal, such as the invention patent with the publication number CN109327141A and the invention patent with the publication number CN102931825A. The voltage regulation range of this kind of voltage stabilizing device is very limited, can not provide the power supply voltage in a wide range, and there are few types of electrical eq...
