Therefore, the main function of adding bypass diode D2 is:
In the process of restarting after input power failure, the VCC of the PIC control IC is greater than UVLO. Under the condition of no soft start, the maximum peak current of the PFC inductor and the power MOSFET is reduced, thereby preventing the power MOSFET from being damaged by high current impact and the linear region. Damaged work.
The PFC inductor saturation current margin is not enough, and the power MOSFET is more likely to be damaged when the high current is saturated.
