Abstract:
An inverter capacitor module comprising:a plurality of substrates including: a plurality of ceramic capacitors provided on top surfaces of each the plurality of substrates; and first and second feeding unit lands having conductive films, said first and second feeding unit lands being arranged on both surfaces of each of said plurality of substrates so as to feed said plurality of ceramic capacitors, the first and second feeding unit lands being electrically connected to each other; a conductive spacer inserted between said plurality of substrates for establishing one of an electrical connection between the first feeding unit lands of an underlying one of the substrates and an overlying one of the substrates, and an electrical connection between the second feeding unit lands of an underlying one of the substrates and an overlying one of the substrates; a fixing element arranged to fix said plurality of substrates in a laminated arrangement via said conductive spacer; and a switching module that is fixed below the bottom substrate among said plurality of substrates that are laminated; wherein said switching module is fixed to said plurality of substrates by said fixing element.
