A bus bar for a plurality of capacitor elements having an equal impedance includes a positive electrode bus bar and a negative electrode bus bar. The positive electrode bus bar and the negative electrode bus bar each includes a main bus bar and branch bus bars. The main bus bar is electrically connected to an electric circuit having a switching element. First ends of the branch bus bars are connected to the main bus bar at different positions, and second ends of the branch bus bars are connected to the capacitor elements. The branch bus bars are configured so that an impedance between the first end and the second end reduces as an impedance between a connecting portion of the main bus bar to the electric circuit and a connecting portion of the first end of the branch bus bar to the main bus bar increases.

A capacitor assembly comprises a plurality of capacitor elements (e.g., four or more capacitor elements) each having a first end surface and a second end surface defining a first polarity terminal and a second polarity terminal, respectively. The plurality of capacitor elements are arranged in at least one stacked pair with a first polarity terminal of a first capacitor element in each stacked pair being opposed to a first polarity terminal of a second capacitor element in such stacked pair. The plurality of capacitor elements in this aspect are contained in a housing. A first polarity bus bar and a second polarity bus bar are electrically connected to the plurality of capacitor elements. The plurality of capacitor elements may be connected in parallel.
