A power converter controlling apparatus operates voltage signals different in phase from phases of commutation voltages of each switching device by 90 degrees to transform the voltage signals and the commutation voltages in conformity with polar coordinate transformation, and operates amplitudes of the commutation voltages and the phase differences of the commutation voltages to a reference phase on the results of the transformation to operate phase-control angles of each switching device on the amplitudes and the phase differences.
Un appareil de commande pour un convertisseur de puissance commande les signaux de tension dont la phase diffère de celle des tensions de commutation de chaque dispositif de commutation par 90 degrés pour transformer les signaux de tension et les tensions de commutation conformément à la transformation des coordonnées polaires, et commande l'amplitude des tensions de commutation et la différence de phase des tensions de commutation en fonction d'une phase de référence pour les résultats de la transformation de façon à commander l'angle de phase de chaque commutateur pour l'amplitude et la différence de phase.
