Title
(EN) CONTROL CIRCUIT FOR CRYOGENICALLY-COOLED POWER ELECTRONICS EMPLOYED IN POWER CONVERSION SYSTEMS
(FR) CIRCUIT DE COMMANDE POUR L'ELECTRONIQUE DE PUISSANCE A REFROIDISSEMENT CRYOGENIQUE UTILISEE DANS DES SYSTEMES DE CONVERSION D'ENERGIE
Abstract
(EN)
A control circuit (21) generates signals for controlling the sequence in which selected input signals are carried across the terminals of a polyphase switching conversion circuit. The control circuit includes switching elements (72-77) galvanically isolated from the selected input signals with the control signals electrically isolated from the switching devices. The control circuit for the conversion circuit is, in essence, electrically isolated from the conversion circuit. The control circuit is configured to have an analogous topology to that of the switching converter and includes conventional switching diodes as well as a light generating device optically coupled to a light sensor which, in response to detection of light from the optically coupled light generating device, provides a control signal to a corresponding switching device. The control circuit also includes a source of regulated and electrically isolated power to operate drive circuitry for the switching devices. The cryogenically cooled switching converter is used to rectify AC input signals generated by a number of variable speed wind-driven turbines.

Un circuit de commande (21) génère des signaux qui commandent la séquence suivant laquelle les signaux d'entrée sont acheminés aux bornes d'un circuit de conversion à commutation polyphasé. Le circuit de commande comprend des éléments de commutation (72-77) galvaniquement isolés des signaux d'entrée sélectionnés, les signaux de commande étant électriquement isolés des dispositifs de commutation. Le circuit de commande destiné au circuit de conversion est, par essence, électriquement isolé du circuit de conversion. Le circuit de commande est configuré de telle manière que sa topologie soit analogue à celle du convertisseur de commutation et comprend plusieurs diodes de commutations classiques ainsi qu'un dispositif générant de la lumière optiquement couplé à un capteur de lumière qui,en réponse à la détection de la lumière émise par le dispositif générant de la lumière optiquement couplé, envoie un signal de commande à un dispositif de commutation correspondant. Le circuit de commande comprend également une source de puissance régulée et électriquement isolée qui sert à faire fonctionner le circuit d'excitation des dispositifs de commutation. Le convertisseur de commutation à refroidissement cryogénique sert à redresser les signaux d'entrée à courant alternatif générés par une pluralité de turbines entraînées par le vent à vitesse variable.
