Description
このような従来技術では、半導体モジュールをヒートシンクに押し付けるために、バネ部材および補強梁が必要となる。このため、従来の電力変換装置は、部品点数が多くなっていた。さらに、従来の電力変換装置は、部品点数が多くなることによって、筐体内の構造上の制約が生まれる、あるいは組立工数が増加するなどの課題があった。
図1は、本発明の実施の形態1における電力変換装置の斜視展開図である。また、図2は、本発明の実施の形態1における図1の構成を備えた電力変換装置の断面図である。
図3は、本発明の実施の形態2における電力変換装置の斜視展開図である。また、図4は、本発明の実施の形態2における図3の構成を備えた電力変換装置の断面図である。
図5は、本発明の実施の形態3における電力変換装置の斜視展開図である。また、図6は、本発明の実施の形態3における図5の構成を備えた電力変換装置の断面図である。
図7は、本発明の実施の形態4における電力変換装置の斜視展開図である。また、図8は、本発明の実施の形態4における図7の構成を備えた電力変換装置の断面図である。
図9は、本発明の実施の形態5における電力変換装置の斜視展開図である。また、図10は、本発明の実施の形態5における図9の構成を備えた電力変換装置の断面図である。
図11は、本発明の実施の形態6における電力変換装置の斜視展開図である。本実施の形態6では、筐体30に複数の橋状構造31が設けられている。このような構成を採用することで、半導体モジュール50の配置数を増加させることができる。
