POWER SYSTEM

A power system includes a power converter and a control device . The power converter includes a first converter circuit including switching legs and a second converter circuit including switching legs . The control device operates the power converter under any one control mode among a charging mode for charging a high-voltage battery B by causing the converter circuits to operate as a PFC converter, a power feeding mode for feeding power to an external AC load EL by causing the second converter circuit to operate as an inverter, and a power feeding during charging mode for feeding power to the external AC load EL while charging the high-voltage battery B by causing the first converter circuit to operate as the PFC converter and causing the second converter circuit to operate as the inverter.
