Its main function is to convert the AC power of the power grid into a stable DC power supply suitable for various components inside the computer. At present, the voltage stabilizing power supplies used in the market do not have a protection function. In the process of short circuit in the control circuit, it is easy to burn the power supply device and equipment.

In order to solve this technical problem, an output circuit 1 and an input circuit 2 are added on this basis.

[0024] More specifically:

[0025] like Figure 1 to Figure 2 As shown:

[0026] In combination with the above content: the input circuit 2 includes a power supply body 21 and an AC triangle switch 22 connected in series to the power supply body 21;
