<p>A method for simplifying short circuit failure mode (SCFM) transitions in a power electronics module. The method includes keeping at least one switch (101, 102, 103, 104) in closed position by means of a signal (109) supplied by a gate unit (110). Upon a failure of a first semiconductor chip (105) during which the failed chip enters an SCFM, the switch (102, 103, 104) is opened, wherein the gates of the second semiconductor chips (106, 107, 108) become floating. Thereby the blocking voltage of the semiconductor chips is reduced.</p> |
