Abstract
A power semiconductor module including a cascade circuit of a low-voltage high-current MOSFET and of a bipolar semiconductor element, for example a field-controlled thyristor, GTO thyristor or Darlington transistor, as a hybrid combination. In this manner, it is possible to achieve a construction, which exhibits low induction and which saves space and which at the same time permits efficient cooling of the module.
