Description
正極端子と負極端子との間でレグと直列接続された、スイッチ素子よりも電流定格の高い保護スイッチ素子(58)と、
スイッチ素子の短絡時に保護スイッチ素子を開状態にする制御部(10)と、
レグ、保護スイッチ素子、および、制御部を搭載するプリント基板(50a)と、を有し、
スイッチ素子よりも保護スイッチ素子は熱容量が大きく、
レグと制御部との間に保護スイッチ素子が位置している。
図1〜図3に基づいて本実施形態にかかるモータ制御装置100を説明する。モータ制御装置100は、図示しない上位ECUからの要求指令に基づいてモータ200を制御する。モータ制御装置100とモータ200とによって、いわゆるISGが構成されている。ISGはIntegrated Starter Generatorの略である。
本実施形態ではモータ200はベルトを介して車両に搭載された内燃機関のクランクシャフトと連結されている例を示した。しかしながらモータ200は動力分配機構を介してクランクシャフトと連結された構成を採用することもできる。
