Abstract
A power source system includes a first battery string, a second battery string, and a third battery string. Each of the battery strings includes a plurality of batteries capable of outputting direct-current power. The battery strings are Y-connected so as to output three-phase alternating-current power to three-phase output terminals (alternating-current output terminals) as well as connected to a neutral line. On the neutral line, a neutral line capacitor for blocking a direct current, a neutral line switch disposed in series to the neutral line capacitor, and an electric resistance element disposed in parallel to the neutral line switch are provided.
