PASSIVE CIRCUIT FOR IMPROVED FAILURE MODE HANDLING IN POWER ELECTRONICS MODULES

摘要

A power electronics module (100) for enhancing short circuit failure mode (SCFM) transitions. The module is adapted to disconnect a gate unit (102) from the module using a first switch (104), upon a failure of at least one of a plurality of semiconductor chips (201) during which the failed chip enters an SCFM, and connect a passive circuit arrangement (103), including at 5 least one capacitor (106) and at least one resistor (107), to the module using a second switch (105). The passive circuit arrangement is adapted to switch on at least one of the remaining non- failed semiconductor chips.
