Title
(JA) 故障診断方法、電力変換装置、モータモジュールおよび電動パワーステアリング装置
Abstract
(JA)

本開示の実施形態に係る故障診断方法は、電源101からの電力をモータ200に供給する電力に変換する電力変換装置1000の故障を診断する。故障診断方法は、少なくとも一相の中に故障した相があるか判定するステップと、少なくとも1つのHブリッジのハイサイドおよびローサイドの中に故障したパートがあるか判定するステップと、第1インバータおよび第2インバータの中に故障したインバータがあるか判定するステップと、故障した相があるかの判定結果、故障したパートがあるかの判定結果および故障したインバータがあるかの判定結果に基づいて、故障したスイッチ素子があるか判定するステップと、を包含する。
