CA 2643110
In order to provide an apparatus having power semiconductor modules, which are connected to one another via connection means so as to form a series circuit, wherein a short-circuiting device (1) for short-circuiting the respective power semiconductor module is assigned to each power semiconductor module, which apparatus has a reliable and at the same time cost-effective short-circuiting device, the invention proposes that the short-circuiting device is a pyrotechnical/mechanical element (1), which has a detonation charge and a tripping means (9), which can be displaced by means of the detonation charge.
Afin de réaliser un dispositif avec des modules de puissance semi-conducteurs, qui sont connectés entre eux par des moyens de connexion par mise en place d'une connexion en série, un dispositif de mise en court-circuit (1) étant appliqué à chaque module de puissance semi-conducteur pour le mettre en court-circuit, le dispositif comportant un dispositif de mise en court-circuit à la fois fiable et économique, il est prévu selon l'invention que le dispositif de mise en court-circuit soit un élément (1) pyrotechnique mécanique qui comporte une charge explosive et un déclencheur (9) pouvant être activé par la charge explosive.
