Abstract
본 발명은 릴레이 및 시간지연형 릴레이구동수단을 이용하여 돌입전류차단용 저항의 사용시간이 소정시간경과되면 릴레이에 의해 전원공급동작이 행해지도록 하므로써 돌입전류차단용 저항을 보호함과 더불어 그 저항에 의한 전원손실을 방지하도록 된 돌입전류차단용 저항 보호회로를 제공하기 위한 것이다.The present invention protects the inrush current blocking resistance by providing a power supply operation by the relay when the use time of the inrush current blocking resistor has elapsed using a relay and a time delay type relay driving means. It is to provide a resistance protection circuit for inrush current blocking to prevent power loss caused by.
이를 위해 본 발명은, AC플러그(1)로부터 인가되는 교류전원을 직류전원으로 정류하는 정류부(10)와, 캐패시터(CI)를 통해 평활화된 상기 정류부(10)로부터의 직류전원을 입력받아 후단의 각 부하회로의 소정의 동작 전원을 출력하는 SMPS회로부(12)를 구비하고, 상기 AC플로그(1)와 정류부(10) 사이에는 상기 AC플러그(1)로부터 입력되는 전원중의 돌입전류를 차단하기 위한 저항(R1)이 접속되어 있는 전기기기의 전원공급회로에서, 상기 저항(R1)에 대해 병렬로 접속된 릴레이(RYC,RYS)와, 상기 AC플러그(1)로부터의 교류전원입력시간이 소정시간을 경과하게 되면 상기 릴레이(RYC,RYS)를 통해 소정의 교류전원이 상기 정류부(10)로 인가되도록 하는 릴레이구동부(18)로 구성되고, 상기 릴레이구동부(18)는 스텐바이전원생성용 정류기(16)로부터의 직류전원을 소정의 충전시정수를 기초로 충전하게 되는 충전시정수소자(R3,C2)와, 상기 충전시정수 소자(R3,C2)에 충전되는 충전량을 기초로 온/오프스위칭하는 스위칭소자로 구성된 것이다.To this end, the present invention, the rectifying unit 10 for rectifying the AC power applied from the AC plug (1) and the DC power from the rectifying unit (10) smoothed through the capacitor (CI) is received in the rear stage An SMPS circuit portion 12 for outputting predetermined operating power of each load circuit is provided, and the inrush current in the power input from the AC plug 1 is interrupted between the AC plug 1 and the rectifier 10. In the power supply circuit of the electric machine to which the resistor R1 is connected, a relay RRY and RYS connected in parallel with the resistor R1 and an AC power input time from the AC plug 1 are predetermined. When time passes, the relay driving unit 18 is configured to allow a predetermined AC power to be applied to the rectifying unit 10 through the relays RIC and RYS, and the relay driving unit 18 is a standby power generation rectifier. At the time of predetermined charge the DC power supply from (16) The charging time constant elements R3 and C2 to be charged based on an integer and a switching element to be switched on / off based on the charge amount charged to the charging time constant elements R3 and C2.
