Claim Text:
1. A power converter that includes a filter capacitor that receives a direct-current voltage from a direct-current power supply and an inverter unit that drives a load using electric energy accumulated in the filter capacitor, wherein in the filter capacitor, a plurality of capacitor elements connected in parallel are provided and a first direct-current terminal, which includes a positive-electrode-side main terminal and a negative-electrode-side main terminal that receive a direct-current voltage from the direct-current power supply, is provided, a first capacitor element is located on one end side in an electrical connection form among the capacitor elements, and a second capacitor element is located on another end side in the electrical connection form, a first conductor portion electrically connects a positive-electrode-side terminal of the first capacitor element to the positive-electrode-side main terminal of the first direct-current terminal, a second conductor portion electrically connects a positive-electrode-side terminal of and the second capacitor element to the positive-electrode-side main terminal of the first direct-current terminal, an inductance component of the first conductor portion and an inductance component of the second conductor portion are configured to be the same value, a third conductor portion electrically connects a negative-electrode-side terminal of the first capacitor element to a negative-electrode-side main terminal of the first direct-current terminal; a fourth conductor portion electrically connects a negative-electrode-side terminal of the second capacitor element to a negative-electrode-side main terminal of the first direct-current terminal; and an inductance component of the third conductor portion and an inductance component of the fourth conductor portion are configured to be the same value.
