- 高電圧バッテリの直流電圧をスイッチングして低電圧の直流電圧に変換する電圧変換部を有し、前記電圧変換部で変換された直流電圧を、負荷とこの負荷へ電力を供給する低電圧バッテリとが接続された電源ラインへ出力する電圧変換装置において、
前記電圧変換部の出力側の電圧を検出する電圧検出部と、
前記電圧検出部で検出された電圧にリップルが含まれているか否かを判別し、当該判別結果に基づいて、前記負荷への電力供給元が前記高電圧バッテリであるか前記低電圧バッテリであるかを判定する判定手段と、を備え、
前記判定手段は、
前記電圧検出部で検出された電圧にリップルが含まれている場合は、前記電力供給元が前記高電圧バッテリであると判定し、
前記電圧検出部で検出された電圧にリップルが含まれていない場合は、前記電力供給元が前記低電圧バッテリであると判定し、
さらに、前記電圧検出部で検出された電圧の値が、あらかじめ定められた所定範囲にあるか否かを検証し、
当該電圧値が所定範囲にない場合に、判定した電力供給元が前記高電圧バッテリであれば、当該高電圧バッテリ側で異常が発生したと判断し、判定した電力供給元が前記低電圧バッテリであれば、当該低電圧バッテリ側で異常が発生したと判断することを特徴とする電圧変換装置。 - 請求項1に記載の電圧変換装置において、
前記判定手段は、前記電圧変換装置の動作状態を示す信号を上位装置から取得し、当該動作状態と、前記リップル有無の判別結果と、前記電圧検出部で検出された電圧の値が前記所定範囲にあるか否かの検証結果とに基づいて、前記高電圧バッテリと前記低電圧バッテリのいずれの側で異常が発生したかを判断することを特徴とする電圧変換装置。 - 請求項2に記載の電圧変換装置において、
前記判定手段は、前記動作状態を示す信号が動作指令信号である場合に、
前記電圧検出部で検出された電圧にリップルが含まれておらず、かつ、当該電圧の値が前記所定範囲にあるときは、高電圧バッテリ側で異常が発生したと判断し、
前記電圧検出部で検出された電圧にリップルが含まれておらず、かつ、当該電圧の値が前記所定範囲にないときは、高電圧バッテリ側および低電圧バッテリ側で異常が発生したと判断することを特徴とする電圧変換装置。
