Abstract
(EN)
This power conversion device is provided with: switching units (10, 10a-10e) that include first switching elements (11, 111, 112) and second switching elements (12, 12a, 121, 122) having a saturation voltage different from that of the first switching elements and connected in parallel to the first switching elements; and driving units (20, 20a-20c, 30, 30a, 30b) that individually drive the first and second switching elements. The driving units set the number of switching times of the second switching elements equal to or less than that of the first switching elements in a voltage region where the on-voltage of the first switching elements is equal to or lower than the intercept of the on-voltage of the second switching elements.

La présente invention concerne un dispositif de conversion de courant, comportant : des unités de commutation (10, 10a-10e) qui comprennent des premiers éléments de commutation (11, 111, 112) et des seconds éléments de commutation (12, 12a, 121, 122) dont la tension de saturation est différente de celle des premiers éléments de commutation et qui sont connectés en parallèle aux premiers éléments de commutation ; et des unités d'attaque (20, 20a-20c, 30, 30a, 30b) qui attaquent individuellement les premiers et seconds éléments de commutation. Les unités d'attaque définissent le nombre d'occurrences de commutation des seconds éléments de commutation égal ou inférieur à celui des premiers éléments de commutation dans une zone de tension où la tension à l'état passant des premiers éléments de commutation est égale ou inférieure au point d'interception de la tension à l'état passant des seconds éléments de commutation.
