Abstract[English]
A method to provide power to a control supporting circuit includes connecting an optical power converter to the control support circuit, the optical power converter connected to a laser source via a fiber optic cable, controlling, by a controller, a laser source driver to drive a laser source providing a laser and the control supporting circuit; and supplying power to the control supporting circuit by irradiating the optical power converter with the laser via the fiber optic cable. A stray capacitance between the controller and the high voltage supporting circuit is reduced to zero or nearly zero. A method of shutting down a laser source driver providing laser energy to an optical power converter is also provided.[French]
Un procédé permettant de fournir de l'énergie à un circuit de support de commande consiste à connecter un convertisseur de puissance optique au circuit de support de commande, le convertisseur de puissance optique étant connecté à une source laser par l'intermédiaire d'un câble à fibre optique, à commander, par un dispositif de commande, un pilote de source laser afin de piloter une source laser générant un laser et le circuit de support de commande ; et à fournir de l'énergie au circuit de support de commande par irradiation du convertisseur de puissance optique avec le laser au moyen du câble à fibre optique. Une capacité parasite entre le dispositif de commande et le circuit de support haute tension est réduite à zéro ou presque à zéro. L'invention concerne également un procédé d'arrêt d'un pilote de source laser fournissant de l'énergie laser à un convertisseur de puissance optique.
