At the same time, the VGS voltage of the power MOSFET is relatively low, which is approximately equal to the UVLO voltage of the VCC of the PFC control IC. If the saturation current of the power MOSFET is relatively low, it may enter the linear region to work, which is more likely to cause the power MOSFET to work in the linear region and be damaged.
If the current sampling resistor RS is in the driving loop of the power MOSFET, it is the ground of the PFC control IC and is not directly connected to the source S of the power MOSFET, the actual voltage of the VGS of the power MOSFET is:
VGS=VCC-VDRH-VRS
Among them, VDRH is the conduction voltage drop of the upper tube of the totem pole inside the PFC control IC.
