Reduce the surge current of the diode D1 of the PFC, because D1 is a fast recovery diode, and the ability to resist surge current is relatively poor.
This explanation seems to have a bit of truth. D1 is a fast recovery diode, which has a weak ability to withstand inrush current, and D2 is an ordinary diode, which has a strong ability to withstand inrush current. However, in practical applications, if no bypass is added Diodes D2 and D1 are rarely damaged due to inrush current, because the output diode D1 is connected in series with the PFC inductor, the PFC inductance is large, and the inherent characteristic of the inductance is that its current cannot be abruptly changed. Therefore, the main function of the bypass diode D2 is not to protect the output diode D1.
