Abstract

본 발명은 인버터 냉각용 팬 제어장치에 관한 것으로 특히, 스위칭 모드 파워 서플라이의 출력단자와 팬사이에서 마이컴에 의해 선택적으로 온/오프되어 팬의 공급전압을 제어하는 스위치와, 상기 교류전동기에 소정의 전류가 흐르는지를 검출하여 실제전류가 흐르면 상기 스위치를 “온”시키고 전류가 흐르지 않으면 “오프”시키는 마이컴을 부가시켜 인버터 제어용 마이컴에서 인버터의 출력전류를 검출하여 열이 실제로 발생되는 상황에서만 팬이 작동될 수 있도록 하므로써, 불필요한 팬의 작동을 억제시킬 수 있어 팬의 수명을 연장시킬 수 있음은 물론 불필요한 전력소모를 사전에 방지할 수 있는 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fan control device for inverter cooling, and in particular, a switch for selectively controlling the supply voltage of a fan by being selectively turned on / off by a microcomputer between an output terminal and a fan of a switching mode power supply, Detects whether the current flows and adds a microcomputer that turns on the switch when the actual current flows and turns off if the current does not flow, and detects the output current of the inverter in the inverter control microcomputer, and the fan operates only when heat is actually generated. By making it possible, unnecessary fan operation can be suppressed to extend the life of the fan and to prevent unnecessary power consumption in advance.
