Title
(EN) Device for short-circuiting power semiconductor modules
Abstract
(EN)

An apparatus has power semiconductor modules, which are connected to one another via connection devices so as to form a series circuit. A short-circuiting device for short-circuiting the respective power semiconductor module is assigned to each power semiconductor module. The apparatus has a reliable and at the same time cost-effective short-circuiting device. It is proposed that the short-circuiting device is a pyrotechnical/mechanical element, which has a detonation charge and a tripping device, which can be displaced by the detonation charge.
