Abstract
Description
以下、本願の実施の形態1の構成について、図1から図4に従って説明する。図1に実施の形態1に係わる半導体装置100の外観を示す。また、図2にこの装置の全体構成を各構成要素に展開した斜視図を示す。図1および図2において、支持部材1に冷却板2を介して電力変換を行う半導体モジュール3a、3b、3c(以降複数ある場合は3a〜3cのように記載)が配置される。半導体モジュール3a〜3cは金属板4によって覆われ、その上に半導体モジュール3a〜3cの電力変換を制御するための制御基板5が設けられている。制御基板5は金属板4に設けられた制御基板固定部6a〜6gによって固定される。制御基板固定部6aは半導体モジュール3a〜3cの配置面に対向して設けられ、制御基板5の固定強度を向上させている。なお、金属板4以外の箇所に設けられる制御基板固定部6h〜6kもあり、制御基板5の端部を固定している。
以下、本願の実施の形態2について図9に基づいて説明する。図9は図6と同様の主要部断面図である。図9に示すように、本実施の形態の半導体装置は支持部材1と、冷却板2と、冷却板2に取り付けられ電力変換を行う半導体モジュール3a〜3cと、冷却板2上に配置される第一の金属板4bと、第一の金属板4bの上に取り付けられた第一の制御基板5aと、第一の金属板4b上に取り付けられる第二の金属板4cと第二の金属板4c上に配置される第二の制御基板5bと、冷却水流路を構成する下板8からなる。本図では省略しているが通常、第一の制御基板5aと第二の制御基板5bはFPCまたはハーネス、あるいは基板間コネクタ等を使い接続されている。
