1. A power conversion apparatus comprising:
a plurality of capacitor units each comprising at least one capacitor charged with electric power fed from a power source;
a plurality of power converters each comprising primary terminals, secondary terminals, and switching elements, the primary terminals of the power converter being connected to a corresponding capacitor unit among the capacitor units, the power converter being configured to convert electric power fed via the primary terminals into electric power to be fed to a load connected to the secondary terminals by means of switching between on and off states of the switching elements and feed the converted electric power via the secondary terminals to the load;
a base having a main surface to which the switching elements of each of the power converters are fixed;
at least one coupling member fixed to some of the capacitor units adjacent to each other; and
a plurality of fitting members each fixed to a corresponding capacitor unit among the capacitor units and fixed to the base, wherein
the capacitor units are disposed along the main surface of the base,
the fitting members are fixed to capacitor units located on both sides among the capacitor units disposed along the main surface, and
the at least one coupling member comprises at least one pair of first coupling members extending along the main surface of the base and facing each other with a space therebetween in a direction intersecting the main surface of the base.
