The switching tubes Q1 and Q2 are controlled by the pulse width modulator to be alternately switched on and off, so that direct current is converted into high-frequency alternating current. The high-frequency oscillating voltage is transformed to be output by a T1 secondary winding in two paths. One path is a chip power supply circuit, the rectifying and filtering circuit obtains about 12V direct current voltage to supply the pulse width modulator for special use, and the other path uses VD1, VD2 and L1 rectifying and filtering as direct current main output.

Meanwhile, the output feedback circuit utilizes the error amplifier as overcurrent protection, and when the differential voltage is greater than a set value, the output of the pulse signal is turned over and closed, so that the overcurrent protection effect is realized.
