Abstract

Onduleur à plusieurs valves à commutation forcée, à fréquence variable, commandée par une chaîne de réglage fournissant un signal de consigne de la fréquence de l'onduleur. L'invention est caractérisée en ce que la consigne de fréquence commande un générateur d'impulsions pour varier la cadence des impulsions qui est n fois plus élevée que la fréquence désirée de l'onduleur, en ce qu'un commutateur cyclique à n positions est actionné par les impulsions et en ce que n ensembles de consignes de commande préétablies sont emmagasinées dans une mémoire et appliqués par ledit commutateur aux électrodes de commande des valves de l'onduleur. Applicable à la commande de vitesse de moteurs asynchrones.Inverter with several forced-switching valves, variable frequency, controlled by an adjustment chain providing a reference signal of the frequency of the inverter. The invention is characterized in that the frequency reference controls a pulse generator to vary the rate of the pulses which is n times higher than the desired frequency of the inverter, in that a cyclic switch with n positions is actuated by the pulses and in that n sets of pre-established control instructions are stored in a memory and applied by said switch to the control electrodes of the valves of the inverter. Applicable to the speed control of asynchronous motors.
