Abstract
(EN) A power conversion device 1 includes a plurality of switching elements, and comprises: a matrix converter circuit 10 that performs bidirectional power conversion between an alternating current power of a primary side and an alternating current power of a secondary side; a power conversion control unit 114 that switches the plurality of switching elements on/off in conjunction with a carrier wave, so as to cause the alternating current of the secondary side to follow a control command; and a carrier wave change unit 116 that changes the frequency of the carrier wave on the basis of proximity level between the frequency of the primary side and the frequency of the secondary side.
(FR) Un dispositif de conversion d'énergie (1) comprend une pluralité d'éléments de commutation, et comprend : un circuit de convertisseur matriciel (10) qui réalise une conversion d'énergie bidirectionnelle entre un courant alternatif d'un côté primaire et un courant alternatif d'un côté secondaire ; une unité de commande de conversion d'énergie (114) qui commute la pluralité d'éléments de commutation en marche/arrêt conjointement avec une onde porteuse, de manière à amener le courant alternatif du côté secondaire à suivre une instruction de commande ; et une unité de modification d'onde porteuse (116) qui modifie la fréquence de l'onde porteuse sur la base d'un niveau de proximité entre la fréquence du côté primaire et la fréquence du côté secondaire.
(JA) 電力変換装置1は、複数のスイッチング素子を有し、一次側の交流電力と二次側の交流電力との双方向の電力変換を行うマトリクスコンバータ回路10と、二次側の交流を制御指令に追従させるように、キャリア波に連動して複数のスイッチング素子のオン・オフを切り替える電力変換制御部114と、一次側の周波数と二次側の周波数との近接レベルに基づいて、キャリア波の周波数を変更するキャリア波変更部116と、を備える。
