LM317 adaptive adjustable regulated voltage supply circuit diagram

Published:2011/3/28 22:55:00 Author:Ecco | Keyword: regulated voltage supply

The power supply is LM317 regulated voltage components, which is use in adaptive circuitry. According to the output voltage , the circuitry will change the input voltage automatically to reduce the differential pressure between the input and output. And that can reduce the power cost of the power supply itself. Among them, VD5, VW, VT2 R5, R6, C10 and relay K constitute of adaptive switching action circuit, when output voltage Vo is lower than 14V, Vw will be stopped as lacking of breakdown voltage and no current pass it, VT2, K stop and K-1 is in closed state, the 14 V secondary voltage of transformer alternating current access regulated voltage circuitry. Or, when the output voltage is higher than 14V, VW is brokendown, VT2 is conducted. K gets electron, and K-1 moves to make 280V ac voltage access circuitry. Ensuring the differential pressure between the input and output does not exceed 15V. The output of the circuitry is continuously adjustable in 1.25 ~ 30V, and the maximum current is 3A.   (View)
