Analysis of a power supply, usually starting from the input. One end of the 220 V communication input is through a 4007 half wave rectifier. The 10 ohm resistor is used for maintenance. If there is a fault at the back that causes over-current, the resistor will be burned out, and then it will avoid causing more serious problems. 4007, 4700pf, 82k on the right Ω When the switch tube 13003 is turned off, it acts as the induced voltage on the absorption coil, and then avoids the breakdown caused by the high voltage added to the switch tube 13003. 13003 is a switch tube (good name should be mje13003), with a withstand voltage of 400V, a maximum collector current of 1.5A, and a maximum collector power consumption of 14W. It is used to control the on-off between the primary winding and the power supply. When the primary winding keeps on and off, it will form a changed magnetic field in the switching transformer, and then induce voltage in the secondary winding.
