Power protecting device and controlling method thereof

Abstract

The disclosure discloses a power protecting device. The power protecting device comprises an input power source coupled to a first capacitor at a first node, configured to provide an input voltage signal; a first switch coupled to the first capacitor; a first resistor coupled to the first capacitor and connected in parallel with the first switch; and an absorber circuit coupled to the first node or coupled to the first node through the first capacitor, wherein the absorber circuit is coupled between the input power source and the first switch, and the absorber circuit is connected in parallel with each of the first switch and the first resistor, or the absorber circuit is coupled to the first capacitor, the first switch and the first resistor, and the absorber circuit is connected in parallel with a combo of the first capacitor, the first switch, and the first resistor.
