Title (EN) DRIVE SYSTEM
(FR) SYSTÈME DE PILOTAGE
(JA) 駆動システム
Abstract:
(EN) A drive system is provided with: a first inverter (51) electrically connected to a first AC rotating machine (20); a second inverter (52) electrically connected to the first end side of each of phase windings (30U, 30V, 30W) constituting a second AC rotating machine (30); a boost converter (50); and a third inverter (53) electrically connected to the second end side of each of the phase windings and transferring power between the phase windings and a second DC power supply (61) different from a first DC power supply (60, 60a) to drive the second AC rotating machine. The drive system is configured so that the second DC power supply and the first AC rotating machine are connected to each other through a single connection route. The drive system is provided with a processing unit (85) for changing the control state of at least one of the first to third inverters and the boost converter on the basis of the state of at least one of the first to third inverters, the boost converter, and the first and second DC power supplies.
(FR) Un système de pilotage comporte : un premier onduleur (51) connecté électriquement à une première machine électrique rotative CA (20) ; un deuxième onduleur (52) connecté électriquement au premier côté d'extrémité de chacun des enroulements de phase (30U, 30V, 30W) constituant une deuxième machine électrique rotative CA (30) ; un convertisseur élévateur (50) ; et un troisième onduleur (53) connecté électriquement au deuxième côté d'extrémité de chacun des enroulements de phase et transférant la puissance entre les enroulements de phase et une deuxième alimentation CC (61) différente d'une première alimentation CC (60, 60a) pour piloter la deuxième machine tournante CA. Le système de pilotage est conçu de telle sorte que la deuxième alimentation électrique CC et la première machine électrique rotative CA sont connectées l'une à l'autre par une ligne de connexion unique. Le système de pilotage est pourvu d'une unité de traitement (85) pour modifier l'état de commande d'au moins un onduleur parmi les premier au troisième onduleurs et du convertisseur élévateur en fonction de l'état d'au moins un onduleur parmi les premier au troisième onduleurs, du convertisseur élévateur, et des première et deuxième alimentations CC.
(JA) 駆動システムは、第1交流回転電機(20)に電気的に接続された第1インバータ(51)、第2交流回転電機(30)を構成する各相巻線(30U,30V,30W)の第1端側に電気的に接続された第2インバータ(52)、昇圧コンバータ(50)、及び上記各相巻線の第2端側に電気的に接続され、第1直流電源(60,60a)とは異なる第2直流電源(61)との間で電力を伝達して第2交流回転電機を駆動する第3インバータ(53)を備える。第2直流電源と第1交流回転電機とが、単一の接続ルートで接続されるように駆動システムが構成されている。駆動システムは、第1~第3インバータ、昇圧コンバータ及び第1,第2直流電源のうち少なくとも1つの状態に基づいて、第1~第3インバータ及び昇圧コンバータのうち少なくとも1つの制御状態を変更する処理部(85)を備える。
