Abstract

See full text

A power starting circuit used in a DC power supply circuit has a double-pole, double-throw switch electrically connected to a positive pole of a DC power supply and controls a conducting state of the circuit. A first capacitor provides a voltage signal for a first switch circuit and controls the conducting state of the first switch circuit in a continuous charging and discharging process. The first switch circuit controls the conducting state of the DC power supply circuit. A maintaining signal input end provides a maintaining signal for the first capacitor. The power starting circuit can achieve an over discharge protection function for the control circuit. Moreover, when the switch is turned on, it can automatically switch the circuit off so as to save power if the electrical product does not need to continue to work.
