Abstract
본 발명은 인버터의 리셋트회로에 관한 것으로, 종래에는 일정전압이 되는 시점에서 마이크로프로세서의 출력이 로우상태가 되면서 스탠바이상태가 되지만 실제로 완전 초기화가 되기 위해서는 상기의 일정전압보다 더 내려가야 하는데 그 지점에 도달하기 전에 전원이 재공급되면 상기 마이크로프로세서는 초기화되지 못하고 계속 스탠바이상태가 되어 버리는 문제점이 있다. 따라서 본 발명은 인버터에 공급되는 전원이 차단되거나 이상사태가 발생하면 인버터의 상태를 정확히 초기화할 수 있도록 하여 안정되고 신뢰성을 향상시킬수 있도록 한다.The present invention relates to a reset circuit of an inverter. In the related art, the output of a microprocessor becomes a standby state when the output of a microprocessor becomes low at a time when a constant voltage is reached, but in order to be completely initialized, the point must be lowered above the constant voltage. If the power is supplied again before the microprocessor is reached, the microprocessor cannot be initialized and is kept in a standby state. Therefore, the present invention enables to initialize the state of the inverter accurately when the power supplied to the inverter is cut off or abnormalities occur, thereby improving the stability and reliability.
