Problems solved by technology

[0003] Since the switching regulator is an electrical device, the water vapor around its working environment will cause corrosion and other effects on the equipment. However, the existing switching regulator products generally do not have the detection function of water vapor in the surrounding environment.

Abstract

The invention discloses a switch voltage stabilizer based on calibration environment humidity changes. A humidity-sensitive sensor module is mounted outside a cabinet of the switch voltage stabilizer, so that when in use, the switch voltage stabilizer can detect changes of humidity in surrounding environment and is well protected. Sensitive material, manufacturing condition and structure of a sensor of the humidity-sensitive sensor module are designed creatively, so that sensitivity of the switch voltage stabilizer is improved greatly, testing repeatability is high, unexpected technological effect is generated, and the switch voltage stabilizer has huge market application prospect.

Description

technical field [0001] The invention belongs to the field of switching voltage regulators, and more specifically relates to a switching voltage regulator based on the change of calibrated ambient humidity. Background technique [0002] Switching regulators use an output stage that repeatedly toggles the "on" and "off" states together with energy storage components to generate an output voltage. [0003] Since the switching regulator is an electrical device, the water vapor around its working environment will cause corrosion and other effects on the equipment. However, the existing switching regulator products generally do not have the detection function of the water vapor in the surrounding environment. Contents of the invention [0004] Aiming at the problems existing in the background technology, the present invention provides a switching voltage regulator based on the change of calibrated ambient humidity. [0005] The object of the present invention is achieved throug...
