Abstract:
(EN) The present invention provides a generator output power control circuit that has a simple configuration and is capable of easily and quickly controlling output power of a rotary-machine-type generator in accordance with the output voltage or rotation speed of the generator. The generator output power control circuit, which generates a duty ratio control voltage applied to a PWMIC, has an output voltage detection unit that detects the output voltage or rotation speed, a plurality of control voltage generation units that individually generate a control voltage, and a control voltage selection unit configured so as to select the voltage having the greatest absolute value among the plurality of control voltages generated by each of the plurality of control voltage generation units. The control voltages generated by the control voltage generation units are proportional, with respect to a prescribed proportion constant, to the amount of increase from a cut-in voltage or a cut-in rotation speed corresponding to a prescribed cut-in point to the output voltage or rotation speed detected by the output voltage detection unit. The duty ratio control voltage is generated on the basis of the control voltage selected by the control voltage selection unit.
(FR) La présente invention concerne un circuit de commande de puissance de sortie de générateur qui présente une configuration simple et pouvant commander facilement et rapidement la puissance de sortie d'un générateur du type machine tournante en fonction de la tension de sortie ou de la vitesse de rotation du générateur. Le circuit de commande de puissance de sortie de générateur, qui génère une tension de commande de rapport cyclique appliquée à un CIMIL, est pourvu d'une unité de détection de tension de sortie qui détecte la tension de sortie ou la vitesse de rotation, d'une pluralité d'unités de génération de tension de commande qui génèrent individuellement une tension de commande, et d'une unité de sélection de tension de commande configurée de façon à sélectionner la tension ayant la plus grande valeur absolue parmi la pluralité de tensions de commande générées par chaque unité de la pluralité d'unités de génération de tension de commande. Les tensions de commande générées par les unités de génération de tension de commande sont proportionnelles, relativement à une constante de proportion prescrite, à la valeur d'augmentation depuis une tension de coupure ou une vitesse de rotation de coupure correspondant à un point de coupure prescrit à la tension de sortie ou à la vitesse de rotation détectée par l'unité de détection de tension de sortie. La tension de commande de rapport cyclique est générée sur la base de la tension de commande sélectionnée par l'unité de sélection de tension de commande.
