Abstract[English]
The present invention relates to an apparatus for converting electrical energy to heat comprising a plurality of modules connected in series arranged between a first and a second de pole, wherein each of the modules has a controllable switchoff type semiconductor switching element. The invention is characterized in that the modules are varistor modules (VM) comprising a varistor (14) arranged in parallel to the switching element (12), and wherein the apparatus (10) further comprises a control system (CS) for controlling the energy conversion, wherein said control system (CS) is configured to actively control a current flowing through the apparatus (10) to equal a preset current reference value by selectively switching the switching elements (12). The present invention further relates to a converter arrangement with the apparatus and a method of operation of the apparatus.[French]
La présente invention concerne un appareil permettant de convertir l'énergie électrique en chaleur comprenant une pluralité de modules connectés en série agencés entre un premier et un second pôle, chacun des modules ayant un élément de commutation à semi-conducteur de type à commutation commandable. L'invention est caractérisée en ce que les modules sont des modules de varistance (VM) comprenant une varistance (14) disposée en parallèle à l'élément de commutation (12), et l'appareil (10) comprenant en outre un système de commande (CS) pour commander la conversion d'énergie, ledit système de commande (CS) étant configuré pour commander activement un courant circulant à travers l'appareil (10) pour qu'il soit égal à une valeur de référence de courant prédéfinie par commutation sélective des éléments de commutation (12). La présente invention concerne en outre un agencement de convertisseur avec l'appareil et un procédé de fonctionnement de l'appareil.
