Patent ID: 10811989

Abstract:
An inverter unit with reduced wiring impedance that includes a switching element unit and a capacitor unit is implemented. A capacitor unit 4 includes first portions 41 with a first length L1 which is a length in a first direction D1 orthogonal to a reference plane R1 of an inverter unit; and second portions 42 with a second length L2 shorter than the first length L1, and the first portions 41 and the second portions 42 are disposed adjacent to each other along the reference plane R1. The switching element unit 3 is disposed so as to overlap the second portions 42 as viewed in the first direction D1, and overlap the first portions 41 as viewed in a second direction D2 which is a direction in which the first portions 41 and the second portions 42 are arranged along the reference plane R1.
