Abstract

본 발명의 순간정전보호장치는, 입력 전원 양단에 연결되어 순간정전 전원을 감지하기 위한 순간정전 감지부와, 순간정전이 감지되면 출력을 차단하여 인버터의 동작을 정지시키기 위한 출력차단부와, 상기 인버터부로 입력되는 전류와 출력차단부의 전류를 비교하여 인버터부로 입력되는 전류가 출력차단부의 최소출력보다 작으면 상기 마이크로 컴퓨터가 출력을 일정시간 정지한 후 다시 초기상태로 복귀하도록 상기 최소출력을 마이크로 컴퓨터에 피드백시키는 피드백부를 포함하여 구성되며, 인버터 구동전원을 직접 감지함으로써 어떠한 경우에도 순간정전의 감지가 가능하며, 이에 따라 인버터 구동을 안정화함으로써 이를 이용하는 제품의 신뢰성을 향상시킬 수 있는 효과가 있다.The instantaneous power failure protection device of the present invention, connected to both ends of the input power supply instantaneous power failure detection unit for detecting the momentary power supply, when the momentary power failure is detected, the output interruption unit for stopping the operation of the inverter by stopping the output, and If the current input to the inverter section is smaller than the minimum output of the output breaker section by comparing the current inputted to the inverter section with the output of the output breaker section, the microcomputer sets the minimum output so that the microcomputer stops the output for a predetermined time and then returns to the initial state. It is configured to include a feedback unit that feeds back to, and in any case by detecting the drive power directly to the inverter can detect a momentary power, thereby stabilizing the drive of the inverter has the effect of improving the reliability of the product using the same.
