Abstract

A surge current suppression circuit includes a switch, a bypass resistor, a detection resistor, and a comparator. The switch is coupled to a first end of an energy storage capacitor in series, wherein a second end of the energy storage capacitor is coupled to a load and receives an input power source. The bypass resistor is coupled to the switch in parallel. The detection resistor is coupled to the switch in series to generate a detection voltage according to a capacitor current flowing through the energy storage capacitor. The comparator compares the detection voltage with a reference voltage to generate a control signal. When the detection voltage is greater than the reference voltage, the control signal controls the switch to be turned off. When the detection voltage is less than the reference voltage, the control signal controls the main switch to be turned on.
