Abstract

소프트 웨어적으로 전압을 전환시켜 순간 정전시에도 오동작이 발생하지 않도록한 전자기기의 자동 전압 전환 장치에 관한 것으로, 종래에는 하드웨어적으로 전압을 전환시켰으므로 순간 정전시 마이컴이 오동작하게 되어 장치가 파손되며 원가동 상승되는 결점이 있었으나 본 발명에서는 소프트 웨어적으로 전압을 전환시켜 보다 안정된 전압 전환을 하도록해서 상기 결점을 개선시킬수 있다.The present invention relates to an automatic voltage switching device of an electronic device in which a voltage is changed by software so that a malfunction does not occur even during a momentary power failure. In the related art, a microcomputer is malfunctioned during a momentary power failure because the voltage is switched by hardware. In addition, in the present invention, the above-described defects can be improved by switching voltages in software to allow more stable voltage switching.
