Abstract

L'invention concerne un onduleur refroidi par air comprenant des semi-conducteurs de puissance pouvant être mis hors-circuit, dans lequel la puissance de refroidissement est mesurée de telle façon que la température des semi-conducteurs ne dépasse pas un seuil de température critique. A cet effet, l'onduleur est caractérisé en ce qu'il présente des corps de refroidissement agencés de façon optimale qui sont montés, au moins partiellement, thermiquement en parallèle, et en ce qu'il est conçu de manière à fonctionner, sous charge permanente, dans une plage de puissance de 1 à 20 mégawatts, de préférence de 2 à 10 mégawatts.
