Abstract: An auxiliary power supply includes an auxiliary power storage configured to store power that is input to the auxiliary power supply and a control circuit, wherein the control circuit is configured to charge, for a reference time amount after the power is input to the auxiliary power supply, the auxiliary power storage by a first current source having a preset peak current level, determine, after the reference tune amount, that the auxiliary power supply is in a slow charging state when a voltage level that is charged to the auxiliary power storage by the first current source for the reference time amount is lower than a reference voltage level, and increase, in response to the slow charging state, the peak current level to charge the auxiliary power storage by a second current source having the increased peak current level that is greater than the preset peak current level.
