Abstract
A portable power supply including: an internal power source including a first subcore and a second module; an alternating current (AC) power output; a direct current (DC) power output; an input unit receiving power from a external source; a power conversion unit converting the power received from the external source to a first DC power; a subcore charging circuit converting the first DC power to a second DC power used for charging the first subcore; a switched capacitor circuit converting a third DC power output by the first and second subcores to a fourth DC power; an AC power conversion unit converting the fourth DC power to an AC power used for powering a peripheral device connected to the AC power output; and a DC power conversion unit converting the fourth DC power to a fifth DC power used for powering a peripheral device connected to the DC power output.
