An auxiliary power source device for a vehicle is incorporated in an electric vehicle and includes a three-phase inverter that converts an input DC voltage into a desired three-phase AC voltage and applies the three-phase AC voltage to a load. The auxiliary power source device further includes a filter reactor 5 that is connected to respective output terminals of a three-phase inverter 3, a filter capacitor 6 that is connected in a Y-shape at an end on a load side of the filter reactor 5 and is not grounded at a neutral point, and a three-phase transformer 7 that includes primary windings 7a1 to 7a3 that are connected in a Y-shape at the end on the load side of the filter reactor 5 and is grounded at a neutral point and secondary windings 7b1 to 7b3 that are connected in a delta shape.
