Claim 6:
7. The rotating electric machine according to claim 1, wherein:
the power converter converts electric power between a direct-current power supply and a phase winding of each phase of the armature winding;
as a plurality of electrical modules, the plurality of switch modules that include the switching element that controls an energization direction of a current that flows to the phase winding of each phase from the direct-current power supply by a switching operation, and a plurality of capacitor modules that include a smoothing capacitor that suppresses high-frequency vibrations that are generated in the current as a result of the switching operation are provided;
a positive-electrode-side conductor that is connected to a positive-electrode side of the direct-current power supply and a negative-electrode-side conductor that is connected to a negative-electrode side of the direct-current power supply are provided;
the switching element and the smoothing capacitor are connected in parallel between the positive-electrode-side conductor and the negative-electrode-side conductor;
the plurality of switch modules and the plurality of capacitor modules are arranged in an annular shape;
the positive-electrode-side conductor and the negative-electrode-side conductor form an annular shape and are connected to a terminal of each module in an order of array of the switch modules and the capacitor modules in the circumferential direction; and
the capacitor modules are arranged on both sides of the switch module, and capacitances of the smoothing capacitors included in the capacitor modules arranged on both sides thereof are equal to each other.
