Abstract

A power conversion system for converting an input power to an output power, includes: a current limit circuit clamping an input current of the output power to be not exceeding an input current limit during a current clamping state; and a charge quantity regulation circuit converting the output power to a temporary storage power in a temporary storage capacitor during a charging mode, wherein the charge quantity regulation circuit converts the temporary storage power to generate the output power in collaboration with the current limit circuit during a discharging mode. When the input current reaches a current threshold, the charge quantity regulation circuit enters the discharging mode. During the discharging mode, the charge quantity regulation circuit regulates an output voltage of the output power to a target level, wherein the target level is lower than an input voltage of the input power.
