This power supply circuit consists of 12 volt AC power rectifier diodes in the form of VD1... VD4 rectifier bridge circuits.
For rectifier diodes in series power circuits, the maximum rectification,
Even under high forward current, the forward voltage drop of Schottky rectifier diodes is very low, only about 0.4V.
When discussing the RC snubber absorption for the secondary-side rectifier diode in a Flyback circuit
If the voltage ripple on C is greater than 20% of the average value, the C value needs to be increased;
Adopting RCD absorption, the absorbed energy includes two parts: one is the DC energy on capacitor C
