Abstract:
(EN) A power conversion device (100) is provided with: a first invertor (120) connected to one end of a winding (M1, M2, and M3) of each phase of a motor; a second invertor (130) connected to the other end of the winding of each phase; and a switching circuit (110) which has at least one of a first switching element (111) that switches connection/disconnection between the first invertor and a ground and to which a first protective circuit (PC1) is connected in parallel, and a second switching element (112) that switches connection/disconnection between the second invertor and the ground and to which a second protective circuit (PC2) is connected in parallel.
(FR) L’invention concerne un dispositif de conversion d’énergie (100) qui est pourvu : d'un premier onduleur (120) connecté à une extrémité d’un bobinage (M1, M2 et M3) de chaque phase d’un moteur ; d'un second onduleur (130) connecté à l’autre extrémité du bobinage de chaque phase ; d'un circuit de commutation (110) qui possède au moins l’un d’un premier élément de commutation (111), qui commute une connexion/déconnexion entre le premier onduleur et une masse et auquel un premier circuit de protection (PC1) est connecté en parallèle, et d’un second élément de commutation (112), qui commute une connexion/déconnexion entre le second onduleur et la masse et auquel un second circuit de protection (PC2) est connecté en parallèle.
(JA) 電力変換装置(100)は、モータの各相の巻線(M1、M2およびM3)の一端に接続される第1インバータ(120)と、各相の巻線の他端に接続される第2インバータ(130)と、第1インバータとグランドとの接続・非接続を切替え、第1保護回路(PC1)が並列に接続された第1スイッチ素子(111)、および、第2インバータとグランドとの接続・非接続を切替え、第2保護回路(PC2)が並列に接続された第2スイッチ素子(112)の少なくとも1つを有する切替回路(110)と、を備える。
