Description
電力変換装置200は上位の制御装置から指令を受けたりあるいは上位の制御装置に状態を表すデータを送信したりするための通信用のコネクタ21を備えている。コネクタ21からの指令に基づいて制御回路172でモータジェネレータMG1やモータジェネレータMG2、補機用モータ195の制御量を演算し、さらにモータとして運転するか発電機として運転するかを演算し、演算結果に基づいて制御パルスを発生し、ドライバ回路174や補機用パワーモジュール350のドライバ回路350Aへ、上記制御パルスを供給する。補機用パワーモジュール350は専用の制御回路を有しても良い、この場合はコネクタ21からの指令に基づいて上記専用の制御回路が制御パルスを発生し、補機用パワーモジュール350のドライバ回路350Aへ供給する。
