Capacitor module for use in inverter, inverter, and capacitor module

Abstract

The present invention provides a small-sized capacitor module for use in an inverter, which is capable of suppressing the occurrence of unwanted inductance components in an electric connection path and which is suitable for a large current use. The present capacitor module is constituted by: mounting a plurality of ceramic capacitors having first and second terminals and on the first surface of a substrate forming a first conductor on the first surface of the substrate forming a second conductor on the second surface of the substrate electrically connecting first and second terminals and to the first conductor and the second conductor respectively; forming, on the substrate first and second terminal mounting portions where the respective first and second terminals of a switching module are mounted; and electrically connecting the first and second terminal mounting portions to the first and second conductors and respectively.
