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,
When discussing the RC peak absorption problem of the secondary side rectifier diode in Flyback
Choose a larger capacitor (such as 100nF) as capacitor C
Adopting RCD absorption, the absorbed energy includes two parts:
The reverse recovery of rectifier tubes only occurs in continuous operation mode
