Abstract:
(EN) The present invention provides a power conversion device equipped with two inverters, wherein when energizing the winding of a certain phase, the current induced in the winding of another phase is reduced. The power conversion device 100 according to an embodiment converts power from a power supply to power supplied to a motor 200 having n (n is an integer of 3 or more) phase windings. The power conversion device 100 is provided with: a first inverter 110 connected to one end of the winding of each phase of the motor 200; a second inverter 140 connected to the other end of the winding of each phase; and a control circuit 300 for controlling the operations of the first and second inverters 110, 140. The n phase windings include a first phase winding and a second phase winding. The control circuit 300 superimposes a correction wave on a fundamental wave for energizing the second phase winding, said correction wave reducing the current that is induced in the second phase winding by energizing the first phase winding.
(FR) La présente invention concerne un dispositif de conversion de puissance équipé de deux onduleurs, dans lequel, lors de l'excitation de l'enroulement d'une certaine phase, le courant induit dans l'enroulement d'une autre phase est réduit. Le dispositif de conversion de puissance 100 selon un mode de réalisation convertit l'énergie provenant d'une alimentation électrique en énergie fournie à un moteur 200 ayant n (n est un entier supérieur ou égal à 3) enroulements de phase. Le dispositif de conversion de puissance 100 comprend: un premier onduleur 110 qui est connecté à une extrémité de l'enroulement de chaque phase du moteur 200; un second onduleur 140 qui est connecté à l'autre extrémité de l'enroulement de chaque phase; et un circuit de commande 300 qui commande le fonctionnement des premier et second onduleurs 110, 140. Les n enroulements de phase comprennent un premier enroulement de phase et un second enroulement de phase. Le circuit de commande 300 superpose une onde de correction sur une onde fondamentale pour exciter le second enroulement de phase, ladite onde de correction réduisant le courant qui est induit dans le second enroulement de phase par excitation du premier enroulement de phase.
(JA) 2つのインバータを備える電力変換装置において、ある相の巻線に通電したときに別の相の巻線に誘導される誘導電流を低減させる。実施形態に係る電力変換装置100は、電源からの電力を、n相(nは3以上の整数)の巻線を有するモータ200へ供給する電力に変換する。電力変換装置100は、モータ200の各相の巻線の一端に接続される第1インバータ110と、各相の巻線の他端に接続される第2インバータ140と、第1および第2インバータ110、140の動作を制御する制御回路300とを備える。n相の巻線は、第1相の巻線および第2相の巻線を含み、制御回路300は、第1相の巻線への通電により第2相の巻線に誘導される誘導電流を低減する補正波を、第2相の巻線の通電のための基本波に重畳する。
