Abstract
본 발명은 신뢰성이 요구되는 시스템에 있어 순간적인 과전류로 인한 시스템 중단이 일어나지 않도록 하여 신뢰성을 향상시키기 위한 순간적인 과전류 방지 회로가 구비된 모터 구동 장치에 관한 것이다.The present invention relates to a motor driving apparatus provided with an instantaneous overcurrent prevention circuit for improving reliability by preventing a system interruption due to an instantaneous overcurrent in a system requiring reliability.
종래의 모터 구동 장치는 순간적인 과전류로 인하여 퓨즈가 단선되게 되면 전원이 차단되어 모터를 구동시키지 못하는 문제점이 있었다.In the conventional motor driving apparatus, when the fuse is disconnected due to instantaneous overcurrent, there is a problem that the power is cut off and the motor can not be driven.
이것을 해결하기 위해, 본 발명은 전원 공급부로부터 공급된 전원에 따라 전압을 검출하여 출력하는 전압 검출부와, 전압 검출부로부터 검출된 전압을 기준전압과 비교하여 그 결과를 출력하는 비교부와, 비교부로부터 출력된 신호에 따라 전원 스위칭부로 제어신호를 출력하는 전원 스위치 제어부와, 전원 스위치 제어부로부터 출력된 제어 신호에 따라 온/오프되어 전압 검출부로부터 출력된 전원을 모터 구동부로 공급하는 전원 스위칭부로 구성된다.A comparator for comparing the voltage detected by the voltage detector with a reference voltage and outputting a result of the comparison; and a comparator for comparing the voltage detected by the voltage detector with a reference voltage, A power switch control unit for outputting a control signal to the power switching unit according to the output signal, and a power switching unit for turning on / off according to the control signal outputted from the power switch control unit and supplying the power outputted from the voltage detection unit to the motor driving unit.
