| description | A power conversion device switches between PHM control mode and sine wave PWM control mode according to a predetermined condition. The PHM control mode alternately forms, according to an electrical angle, a first period during which upper arm switching elements and lower arm switching elements are each turned on at different phases and current is supplied from a DC power supply to a motor and a second period during which either the upper arm switching elements or the lower arm switching elements are turned on at the all phases to maintain the torque by the energy stored in the motor. The sine wave PWM control mode turns on the switching elements according to the pulse width determined on the basis of the comparison result between a sine wave command signal and a carrier wave and supplies current from the DC power supply to the motor.
L'invention concerne un dispositif de conversion d'énergie qui commute entre un mode de commande de type PHM (Pulse Height Modulation pour Modulation d'Impulsion en Hauteur) et un mode de commande PWM (Pulse Width Modulation pour Modulation d'Impulsion en Largeur) à onde sinusoïdale en fonction d'une condition prédéterminée. Le mode de commande PHM forme en alternance, en fonction d'un angle électrique, une première période pendant laquelle des éléments de commutation de bras supérieur et des éléments de commutation de bras inférieur sont chacun fermés selon des phases différentes et un courant est délivré à un moteur par une alimentation électrique à courant continu, et une seconde période pendant laquelle l'un ou l'autre des éléments de commutation de bras supérieur et des éléments de commutation de bras inférieur sont fermés pour toutes les phases afin de conserver le couple grâce à l'énergie stockée dans le moteur. Le mode de commande PWM à onde sinusoïdale ferme les éléments de commutation en fonction de la largeur d'impulsion déterminée sur la base du résultat de la comparaison entre un signal de commande à onde sinusoïdale et une onde porteuse et délivre au moteur le courant fourni par la source d'alimentation électrique à courant continu. |
