Abstract
A system for a power supply, wherein the power supply is configured to receive an alternating current voltage and supply an output voltage, the system including a switch and a control circuit. The switch receives the alternating current voltage and charges, in response to the power supply receiving the alternating current voltage and not supplying the output voltage, a capacitance to a first voltage. The first voltage is output to a first circuit controlling the power supply while the power supply is receiving the alternating current voltage and not supplying the output voltage. The control circuit deactivates the switch in response to the power supply receiving the alternating current voltage and supplying the output voltage. In response to the control circuit deactivating the switch, the switch stops charging the capacitance, and the first circuit receives the output voltage of the power supply.
