1. An alternating current (AC) power output device that outputs AC power from a plurality of batteries connected in series, the AC power output device comprising:
a switching component connected to each of the plurality of batteries and configured to turn ON or OFF an electrical connection between a corresponding battery and another battery depending on an operational state;
a filter component configured to receive an output voltage from the plurality of batteries, to adjust a polarity of the output voltage from the plurality of batteries according to an operational state, and to output the voltage of the adjusted polarity; and
a controller configured to control the operational states of the switching component and the filter component so that the AC power is output from the plurality of batteries.
