【文字介绍】

A Mosfet (sync. FET) replaces a diode in rectify circuit.
The sync. FET has NO control function.
With a gate-source short on the syn. FET, the system stays electrically function.
Inductive energy is now triggering a LC oscillation circuit and forcing the stored energy in the stray inductances Lstray then to be transferred to Coss so therefore product the turn off overvoltage spike.
The LC circuit is defined by the inductance of the transformer, the layout, the package and the MOSFET Coss
