Title (EN) POWER CONTROLLER
(FR) REGULATEUR DE PUISSANCE
Abstract:
(EN) The power controller for automatically providing a ramp-up and/or ramp-down of electrical power to a load (10). With an A.C. source, the ramp-up or ramp-down is achieved by varying the amplitude or phase angle of the applied voltage. With a D.C. source the ramp-up or ramp-down is achieved by varying the value of the voltage applied to the load (10). The non-linearity of circuit components of the controller is overcome by using the square wave function. The power to the load (10) is provided through load supply networks (11 and 12) on either side of the load which are driven alternatively by a common drive network.
(FR) Régulateur automatique de puissance assurant l'augmentation et/ou la diminution progressives de la puissance électrique appliquée à une charge (10). Lorsque la source est un courant alternatif, l'augmentation ou la diminution est obtenue en faisant varier l'amplitude ou l'angle de phase de la tension appliquée. Lorsque la source est un courant continu, l'augmentation ou la diminution est obtenue par variation de la valeur de la tension appliquée à la charge (10). Le problème de la non-linéarité des composants du circuit du régulateur est résolu par l'utilisation de la fonction d'onde rectangulaire. La puissance appliquée à la charge (10) est fournie par des réseaux d'alimentation (11 et 12) de la charge situés sur les deux côtés de la charge, lesdits réseaux étant excités alternativement par un réseau commun.
