CAPACITOR MODULE AND POWER UNIT

摘要

PROBLEM TO BE SOLVED: To reduce an inductance of a conductor to be a current path.SOLUTION: A capacitor module 100 includes a PN bus bar portion 110 in which a P bus bar and an N bus bar are laminated and capacitors 101 and 102 are mounted on a capacitor mounting area on the PN bus bar portion 110. The capacitor mounting area in the P bus bar and the N bus bar is a main current path of current from a power source. The PN bus bar portion 110 includes: a P electrode pattern layer 113 which is formed between the capacitors 101 and 102 and the P bus bar and N bus bar, and is electrically connected to a capacitor terminal of the capacitors 101 and 102 and electrically connected to the P bus bar outside the capacitor mounting area; and N electrode pattern layers 111 and 112 which are formed between the capacitors 101 and 102 and the P bus bar and N bus bar, and electrically connected to the capacitor terminal of the capacitors 101 and 102 and electrically connected to the N bus bar outside the capacitor mounting area.SELECTED DRAWING: Figure 1
