POWER CONVERSION DEVICE

To provide a power conversion device for reducing parasitic inductance while suppressing increases in size and weight of connection conductors.SOLUTION: A power conversion device includes: a capacitor; a power module that converts and outputs voltage from the capacitor; and a connection conductor that has a positive electrode side bus bar for connecting the capacitor and a P-type terminal of the power module, and a negative electrode side bus bar arranged symmetrically in parallel with the positive electrode side bus bar via a gap and connecting the capacitor to an N-type terminal of the power module. The positive electrode side bus bar includes: a first main body portion that has a first bottom surface coming into contact with the P-type terminal and a first opposing surface rising from the first bottom surface; and a first notch portion that is formed in the first main body on the opposite side of the first bottom surface and the first opposing surface. The negative electrode side bus bar includes: a second main body portion that has a second bottom surface coming into contact with the N-type terminal and a second opposing surface rising from the second bottom surface and arranged opposite to the first opposing surface via the gap; and a second notch portion that is formed in the second main body on the opposite side of the second bottom surface and the second opposing surface.SELECTED DRAWING: Figure 2 【課題】接続導体の大型化及び高重量化を抑制しつつ、寄生インダクタンスを低減する。【解決手段】コンデンサと、コンデンサからの電圧を変換し出力するパワーモジュールと、コンデンサとパワーモジュールのＰ型端子とを接続する正極側バスバーと、正極側バスバーとギャップを介して対称に並設され、コンデンサとパワーモジュールのＮ型端子とを接続する負極側バスバーと、を有する接続導体とを備え、正極側バスバーは、Ｐ型端子に当接する第一底面、及び第一底面から立ち上がる第一対向面を有する第一本体部と、第一底面及び第一対向面とは反対側で第一本体部に形成された第一切り欠き部とを有し、負極側バスバーは、Ｎ型端子に当接する第二底面、及び第二底面から立ち上がり、第一対向面とギャップを介して対向配置された第二対向面を有する第二本体部と、第二底面及び第二対向面とは反対側で第二本体部に形成された第二切り欠き部とを有する電力変換装置。【選択図】図２
