Abstract
A control method and circuit for two-stage current limiting of peak power current are disclosed. The method includes detecting a load current of a power supply system; judging a load current interval of the power supply system; when the load current of the power supply system is less than the rated power current, enabling the system to work in a constant voltage mode; and when the load current of the power supply system is greater than the rated power current, enabling the system to work in a peak power mode; and when the load current of the power supply system is greater than the peak power current, starting a protection program.
