Claim 16:
17. A method for controlling operation of a power supply for an electricity meter during an alternating current (AC) power outage, the method comprising:
receiving, by a power supply control circuit, an AC power loss signal;
generating, by the power supply control circuit, a false feedback signal to the power supply, wherein the false feedback signal is different than a feedback signal generated by an output voltage of the power supply, wherein the false feedback signal causes the power supply to stop supplying the output voltage;
determining that the output voltage of the power supply reached a lower voltage threshold; and
in response to determining that the output voltage of the power supply reached the lower voltage threshold, ceasing generation of the false feedback signal.
