1. An inverter structure of an inverter comprising a smoothing capacitor and a plurality of power modules,
wherein the smoothing capacitor includes a plurality of columnar unit capacitors each having electrodes at both ends thereof, a plate-shaped one-end-side bus plate connected to the electrode at one end of each unit capacitor, and a plate-shaped other-end-side bus plate connected to the electrode at the other end of the unit capacitor, and the unit capacitors are arranged, with axes thereof parallel to each other, side by side in a direction along a plane perpendicular to the axes; and
the power modules are arranged at positions equally distant from a predetermined center of the inverter and equally distant from the smoothing capacitor.
