  • Patent number: 11942869
    Abstract: A power module is applied to an electric power conversion device in which multiple upper-lower arm circuits are connected to an electric power line in parallel. The power module includes the multiple upper-lower arm circuits; a capacitor connected to each of the multiple upper-lower arm circuits in parallel; an upper wiring that connects an upper arm and a positive electrode terminal of the capacitor; a lower wiring that connects a lower arm and a negative electrode of the capacitor; an upper electric power wiring that is an electric power wiring connected to the electric power line and connects a high potential line of the electric power line and the upper wiring; and a lower electric power wiring that is an electric power wiring connected to the electric power line and connects a lower potential line of the electric power line and the lower wiring.
