The element such as V2 and chip IC 1 constitutes control circuit, and circuit is using operational amplifier μ A741 as comparing control element, triode
V1 and V2 works on off state as adjustment element, circuit.As output voltage U1 2mV lower than reference voltage, i.e. chip IC 1
Lower than the 3 pin 2mV of 2 pin (because the reaction sensitivity of μ A741 is 2mV), the 6 pin output high level of chip IC 1 controls V1 and V2
Conducting, with high current as the electric energy supplement such as load and relevant filter capacitor C2, C3, makes output voltage be raised to 12V, i.e. chip quickly
2, the 3 pin current potentials of IC1 are equal.Its 6 pin output low-voltage (2V), V1, V2 are closed, and suspend power supply.Growth over time, output
Voltage is gradually reduced, and repeats said process again, goes round and begins again, and power supply is continuously on off state, and makes output voltage U1 all the time
Stable, running into long-time rainy weather causes the voltage of T to be reduced to when being not enough to holding circuit and running, through resistance R2 and resistance
Undertension after R3 partial pressures to maintain the conducting of triode V3, connect, now by battery by relay K dead electricity, its contact K-1
The voltage that E power supply circuits normally start, realizes the purpose of dual power supply.
