Patent number: 9293909Abstract: A power electronics module for enhancing short circuit failure mode (SCFM) transitions. The module is adapted to disconnect a gate unit from the module using a first switch, upon a failure of at least one of a plurality of semiconductor chips during which the failed chip enters an SCFM, and connect a passive circuit arrangement, including at least one capacitor and at least one resistor, to the module using a second switch. The passive circuit arrangement is adapted to switch on at least one of the remaining non-failed semiconductor chips.Type: GrantFiled: April 20, 2012Date of Patent: March 22, 2016Assignee: ABB RESEARCH LTDInventors: Franz Wildner, Thomas Christen, Thorsten Strassel
