Description
図6は、図5に示す状態からさらに半導体ユニット30の温度検知をするセンサー部7および各パワー半導体素子と制御端子24を繋ぐボンディングワイヤ8を取り除いた本発明の実施形態を明瞭に示す半導体ユニット30の外観斜視図である。
図8は、同様に理解を助けるために図6を断面Eで切断して方向Fから見た時の縦断断面図である。図9は、図6の導体板33及び導体板34を取り除いた半導体ユニット30の外観斜視図である。
上下アーム直列回路121の上下端は、それぞれ、バッテリ200の正極および負極に直流コネクタ140を介して接続される。上側(正極側)に配置されたIGBT31Uとダイオード32Uとからなる電流スイッチ回路は、いわゆる、上アームとして動作する。また、下側(負極側)に配置されたIGBT31Lとダイオード32Lとからなる電流スイッチ回路は、いわゆる、下アームとして動作する。
ここで、ドライバ回路131から出力される信号は、パワー半導体モジュール1の上アームおよび下アームの各IGBT31U、31Lに供給され、そのスイッチング動作を制御して、各上下アーム直列回路121から出力される交流電流u、v、wの振幅や位相などを制御する。
