Power conversion apparatus and electric vehicle

摘要

A power conversion apparatus (200) capable of improving the impedance characteristics between each of two power modules (140, 142) and each of a plurality of capacitor cells (514), the power conversion apparatus (200) including: plural capacitor cells (514) connected in parallel between a three-layer laminated wiring board (313) consisting of a positive polarity conductor board (314) and a negative polarity conductor board (316) formed widely in the direction of the parallel disposition of the power modules (140, 142) and laminated with an insulation sheet (318) therebetween; a three-layer laminated conductor board (313) consisting of a positive polarity conductor board (314) and a negative polarity conductor board (316) formed widely in the direction of the parallel direction of the power modules (140, 142) and laminated with an insulation sheet (318) therebetween and used to connect the positive and negative polarity sides of each of the two power modules (140, 142) to the laminated wiring board (313) respectively.
