Description
図4は、本発明の実施の形態の変形例1のインバータ装置の断面図である。なお、図4においても重力方向は−Z方向である。上述した実施の形態では、密閉空間E1を、基板13aを用いて形成していたが、この変形例1では、密閉空間E1に対応する空間に絶縁紙21を重ねている。この変形例1では、パワー半導体モジュール13に基板13aを持たない場合、あるいは基板13aがインバータ筐体10まで広がっていないものである場合に有効である。
図5は、本発明の実施の形態の変形例2のインバータ装置の断面図である。なお、図5においても重力方向は−Z方向である。この変形例2では、密閉空間E3,E4がパワー半導体モジュール13および冷却面11aを覆うようにしている。この構成は、インバータ筐体10の幅が冷却面11aに比して大きい場合に適している。
