Abstract: The present technology includes a power supply and a method of operating the same. The power supply includes a main power supply configured to receive external power and output a charge voltage and main power, and an auxiliary power supply including a capacitor array configured to charge auxiliary power using the charge voltage and output the auxiliary power. The auxiliary power supply is configured to periodically repeat a discharge operation and a sub charge operation on the capacitor array when the charging of the capacitor array is started.
