(JA) インバータ装置
Abstract:
(EN) An inverter device is provided with: the same number of inverter modules 1a, 1b, 1c as the number of phases of a motor 4; and a snubber circuit 2a connected between the DC terminals of each of the inverter modules 1a, 1b, 1c. The inverter modules 1a, 1b, 1c are each provided with a plurality of switching element pairs of two switching elements connected in series, wherein the switching element pairs are connected in parallel. The switching elements constituting the inverter modules 1a, 1b, 1c are driven by a common drive signal in each of the inverter modules 1a, 1b, 1c.
(FR) L'invention concerne un dispositif onduleur qui est pourvu : du même nombre de modules onduleurs 1a, 1b, 1c que le nombre de phases d'un moteur 4 ; ainsi que d'un circuit d'amortissement 2a connecté entre les bornes à courant continu de chaque module onduleur 1a, 1b, 1c. Chaque module onduleur 1a, 1b, 1c est pourvu de plusieurs paires d'éléments de commutation de deux éléments de commutation connectés en série, les paires d'éléments de commutation étant connectées en parallèle. Les éléments de commutation, qui constituent les modules onduleurs 1a, 1b, 1c, sont attaqués par un signal d'attaque commun dans chaque module onduleur 1a, 1b, 1c.
(JA) インバータ装置は、モータ4の相数と同数のインバータモジュール1a,1b,1c及びインバータモジュール1a,1b,1cの直流端子間に接続されたスナバ回路2aを備える。インバータモジュール1a,1b,1cは、2つのスイッチング素子が直列に接続されたスイッチング素子対を複数備え、複数のスイッチング素子対は並列に接続される。インバータモジュール1a,1b,1cを構成するスイッチング素子は、インバータモジュール1a,1b,1cごとに共通の駆動信号によって駆動される。
