미설명 부호 B+는 릴레이 스위치(RS1)에 인가되는 전원이다.Reference numeral B + is a power source applied to the relay switch RS 1 .

이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

본 고안의 회로도에서 트랜스(T1)의 2차측에 유기된 전원이 브리지다이오드(BD1)와 평활용 콘덴서(C1)를 통하여 직류전원으로 변환된 후 저항(R4)과 레귤레이터(3)를 통하여 출력단자(O1) 후단에 스탠바이 전원을 인가함과 동시에 마이콤(20)를 구동한다.In the circuit diagram of the present invention, the power induced in the secondary side of the transformer (T 1 ) is converted to DC power through the bridge diode (BD 1 ) and the smoothing capacitor (C 1 ), and then the resistor (R 4 ) and the regulator (3). The standby power is applied to the rear end of the output terminal O 1 and the microcomputer 20 is driven at the same time.

여기서 파우어 스위치를 "온"시키게 되면 마이콤(20)의 출력(20)의 출력(P2)측으로부터 「H레벨」이 발생된 후 바이어스 저항(R5)과 잡음제거용 콘덴서(C4)를 통하여 트랜지스터(Q3)를 "턴온"시키고 이때 정류 및 평활부(1)의 출력인 직류전원이 릴레이 코일(L1)과 방향절환용 다이오드(D3) 및 트랜지스터(Q3)를 통하여 접지로 흐름에 따라 코일(L1)이 여자되어 릴레이스위치(RS1)를 "온"시킴으로서 출력단자(O3)후단에 메인전원이 인가될수 있는 것이며 이와 동시에 정류 및 평활부(1)를 통하여 변환된 직류전원이 트랜지스터(Q1)의 베이스측 저항(R1)과 방향 제어용 다이오드(D4) 및 트랜지스터(Q3)를 통하여 접지로 흐름에 따라 트랜지스터(Q1)를 "턴온"시킨후 바이어스저항(R2)(R3)과 정전압용 제너다이오드(ZD1) 및 평활용 콘덴서(C2)를 통하여 트랜지스터(Q2)를 "턴온"시킴으로서 출력단자(O2) 후단에 서브전원이 인출됨과 동시에 방향 제어용 다이오드(D1)와 레귤레이터(3)를 통하여 출력단자(O1) 후단에 스탠바이 전원이 인가될수 있는 것이다.When the power switch is turned on, the "H level" is generated from the output P 2 of the output 20 of the microcomputer 20, and then the bias resistor R 5 and the noise canceling capacitor C 4 are turned on. The transistor Q 3 is "turned on" and the direct current power source, which is the output of the rectifying and smoothing unit 1, is connected to the ground through the relay coil L 1 , the direction switching diode D 3 , and the transistor Q 3 . The coil L 1 is excited as the flow turns on the relay switch RS 1 so that the main power can be applied to the rear end of the output terminal O 3 and at the same time, it is converted through the rectifying and smoothing unit 1. after the base-side resistor (R 1) and the direction for controlling the diode (D 4) and a transistor transistor (Q 1) in accordance with a ground flow through (Q 3) of the direct-current power supply transistor (Q 1) "turn-on" bias resistor Through (R 2 ) (R 3 ) and Zener diode for constant voltage (ZD 1 ) and smoothing capacitor (C 2 ) A transistor (Q 2) to the rear end "turn-on" sikimeuroseo output terminal (O 2) as soon sub power is drawn out to the rear end at the same time, the direction control diode (D 1) and the output terminal (O 1) through the regulator 3 the standby power It can be authorized.

따라서 정류 및 평활부(10)로부터 인출되는 스탠바이 전원이 마이콤(20)을 구동시킨 후 트랜지스터(Q3)를 "턴온"시킴에 따라 트랜지스터(Q1)가 "턴온"되고 릴레이 스위치(RS1)가 "온"됨으로서 출력단자(O2)(O3) 후단에 서브 전원과 메인전원이 인가될 수 있는 것이다.Accordingly, as the standby power source drawn from the rectifying and smoothing unit 10 drives the microcomputer 20 and then turns on the transistor Q 3 , the transistor Q 1 is "turned on" and the relay switch RS 1 . By "on", the sub power and the main power can be applied to the rear end of the output terminal (O 2 ) (O 3 ).

이상에서와 같이 본 고안은 트랜스로부터 인출되는 스탠바이 전원이 마이콤을 구동하게 한후 트랜스 인출 전원을 제어시켜 서브 전원을 인출하게 구성한 것으로 부품수가 절감될수 있으며 과부하시 보호될수 있게한 스탠바이 전원을 이용한 서브 전원 공급회로를 제공할수가 있는 것이다.As described above, the present invention is configured so that the standby power drawn from the transformer drives the microcomputer and then the sub power is drawn out by controlling the transformer draw power and thus the number of parts can be reduced and the sub power supply using the standby power that can be protected in case of overload You can provide a circuit.
