Title
(EN) MULTIPLE MOTOR DRIVE SYSTEM
(FR) SYSTÈME D'ENTRAÎNEMENT DE MOTEUR MULTIPLE
(JA) 複数モータ駆動システム
Abstract
(EN) A polyphase inverter circuit (68) and an H-bridge circuit (671) form an integrated power conversion circuit (60) in which a leg is shared. A DC motor (710) has a first terminal (T1) connected to a single-phase phase current path of a polyphase motor (800) via a first DC current path (P1), and a second terminal (T2) connected to a connection point (M1) for upper and lower arm switching elements in a leg on the unshared side of the H-bridge circuit (671) via a second DC current path (P2). Sections in the first and second DC current paths (P1, P2) that are connected to the first and second terminals (T1, T2) are configured as a total of two individual paths. Noise suppression components (2, 3, 4, 5) that suppress electromagnetic noise generated by conduction are provided across the first and second DC current paths (P1, P2).
(FR) L'invention concerne un circuit onduleur polyphasé (68) et un circuit à pont en H (671) qui forment un circuit intégré de conversion d'énergie (60) dans lequel une branche est partagée. Un moteur à courant continu (710) comporte une première borne (T1) connectée à un trajet de courant de phase monophasé d'un moteur polyphasé (800) par l'intermédiaire d'un premier trajet de courant continu (P1) et une seconde borne (T2) connectée à un point de connexion (M1) pour des éléments de commutation de bras supérieur et inférieur dans une branche sur le côté non partagé du circuit à pont en H (671) par l'intermédiaire d'un second trajet de courant continu (P2). Des sections dans les premier et second trajets de courant continu (P1. P2) qui sont connectées aux première et seconde bornes (T1, T2) sont conçues en un total de deux trajets individuels. Des composants de suppression de bruit (2, 3 4, 5) qui suppriment le bruit électromagnétique généré par la conduction sont fournis à travers les premier et second trajets de courant continu (P1, P2).
(JA) 多相インバータ回路(68)及びHブリッジ回路(671)は、レッグを共有する統合電力変換回路(60)をなしている。直流モータ(710)は、第1端子(T1)が第1直流電流経路(P1)を経由して多相モータ(800)の一相の相電流経路に接続されており、第2端子(T2)が第2直流電流経路(P2)を経由してHブリッジ回路(671)の非共有側のレッグにおける上下アームのスイッチング素子の接続点(M1)に接続されている。第1、第2直流電流経路(P1、P2)における第1、第2端子(T1、T2)に接続される部分は、計2本の個別経路として構成されている。通電により発生する電磁ノイズを抑制するノイズ抑制部品(2、3、4、5)が第1、第2直流電流経路(P1、P2)に跨がって設けられている。
