Abstract
A power supply circuit for providing a DC output signal from an AC input signal by (1) coupling an AC source to the DC output terminal and to a capacitor when the AC input signal is within a preselected AC voltage range thereby providing power to the DC output terminal while charging the capacitor, and (2) uncoupling the AC source from the DC output terminal and the capacitor when the AC input signal is outside of the preselected voltage range, thereby relying on the capacitor to provide power to the DC output terminal.
