As shown in chart, the switching regulator supply circuit is made from three terminal regulator, and the working principle can be understood by the equivalent circuit diagram. For some reason, the output voltage V0 declined slightly, its separate pressure V3 in R5 and R6 fall subsequently, and magnified by VT3, the Ic3 decreases, and Ic2 increases, namely the current flowed through R1 and VD1 increases, V1 drops, V4, Ic1 increase, V2 rises, and cause V3 down... This process is a positive feedback chain reaction, and the last result is that VT1, VT2 are conducted strongly, VT3 stops working, IC1 charges for L1, C1, and Vo rises, then causes a series of positive feedback chain reaction. After a short time, Vo's rising results in the conduction of VT3, the deadline of VT1, VT2. The current stored on L1 released by load and diode VD2, which resulting in V4 dropping to 0. Of course Vo also slowly down until the second flip, namely completes self-excited oscillation of a cycle. The whole circuit works in the cycle of switching state.

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.
