Add bypass diode D2
When the input power supply AC is recharged, the output voltage is quickly charged through the bypass diode D2, which reduces the maximum on-time of the power MOSFET and reduces the maximum working peak current.
● Properly increase the current sampling resistance RS of the PFC
Increasing the current sampling resistance of the PFC can reduce the maximum working peak current, but it is necessary to ensure that the system can work and start normally within the range of full voltage and under full load conditions.
● Check the saturation current of the PFC inductor
Make sure that the saturation current of the PFC inductor is greater than the maximum current value set by the current sampling resistor. At the same time, considering the delay of the current sampling circuit, the saturation current of the PFC inductor has a certain margin.
