Title (EN) POWER CONVERSION DEVICE
(FR) DISPOSITIF DE CONVERSION DE PUISSANCE
(JA) 電力変換装置
Abstract:
(EN) In the present invention, the time period after switching elements S1, S4 which are at first diagonal positions of a full-bridge inverter (2) simultaneously turn OFF and until switching elements S2, S3 which are at second diagonal positions simultaneously turn ON is denoted as T1, the time period after the switching elements S2, S3 which are at the second diagonal positions simultaneously turn OFF and until the switching elements S1, S4 which are at the first diagonal positions simultaneously turn ON is denoted as T2, and control is carried out so that the lengths of T1 and T2 change in each switching cycle while the total length of T1 and T2 is fixed.
(FR) Dans la présente invention, la période après que des éléments de commutation S1, S4 qui se trouvent au niveau de premières positions diagonales d'un onduleur en pont complet (2) s'éteignent simultanément et jusqu'à ce que les éléments de commutation S2, S3 qui se trouvent au niveau de secondes positions diagonales s'allument simultanément est désignée par T1, la période après que les éléments de commutation S2, S3 qui se trouvent au niveau des secondes positions diagonales s'éteignent simultanément et jusqu'à ce que les éléments de commutation S1, S4 qui se trouvent au niveau des premières positions diagonales s'allument simultanément est désignée par T2, et la commande est réalisée de telle sorte que les durées de T1 et T2 changent dans chaque cycle de commutation tandis que la durée totale de T1 et T2 est fixe.
(JA) フルブリッジインバータ(2)の第1対角にあるスイッチング素子S1、S4が同時にオフし、第2対角にあるスイッチング素子S2、S3が同時にオンするまでの期間をT1、第2対角にあるスイッチング素子S2、S3が同時にオフし、第1対角にあるスイッチング素子S1、S4が同時にオンするまでの期間をT2とし、T1およびT2の合計長さを一定にした上で、T1およびT2の長さをスイッチング周期ごとに変化するように制御する。
