CAPACITOR MODULE AND POWER CONVERSION DEVICE

To provide an effective technique for suppressing the influence of conduction noise transmitted from an inverter through a conductor.SOLUTION: A capacitor module 101 includes an energizing unit 20 on a power supply side and an energizing unit 30 on an inverter side. The energizing unit 20 on the power supply side has a first positive conductor 21 electrically connected to a positive electrode surface 11 of a capacitor 10 and a first negative electrode conductor 22 electrically connected to a negative electrode surface 12 of the capacitor 10. The energizing unit 30 on the inverter side has a second positive electrode conductor 31 electrically connected to a positive electrode surface 11 of the capacitor 10 and a second negative electrode conductor 32 electrically connected to the negative electrode surface 12 of the capacitor 10. Both of one pair of positive electrode side parallel running portions 21b and 31b that run in parallel so that the conducting directions are the same in the first positive electrode conductor 21 and the second positive electrode conductor 31 and one pair of negative electrode side parallel running portions 22b and 32b that run in parallel so that the conducting directions are the same in the first negative electrode conductor 22 and the second negative electrode conductor 32 are provided.SELECTED DRAWING: Figure 2 【課題】インバータから導体を通じて伝わる伝導ノイズの影響を抑制するのに有効な技術を提供する。【解決手段】コンデンサモジュール１０１は、電源側通電部２０及びインバータ側通電部３０を備え、電源側通電部２０はコンデンサ１０の正極面１１に電気的に接続される第１正極導体２１とコンデンサ１０の負極面１２に電気的に接続される第１負極導体２２とを有し、インバータ側通電部３０はコンデンサ１０の正極面１１に電気的に接続される第２正極導体３１とコンデンサ１０の負極面１２に電気的に接続される第２負極導体３２とを有し、第１正極導体２１と第２正極導体３１において通電方向が同一となるように並走する一対の正極側並走部２１ｂ，３１ｂと、第１負極導体２２と第２負極導体３２において通電方向が同一となるように並走する一対の負極側並走部２２ｂ，３２ｂと、の両方を備える。【選択図】図２
