摘要： 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.

摘要： A high voltage DC circuit breaker comprises a semiconductor switching assembly (3) in series to a mechanical switch (4). When the semiconductor switching assembly (3) is switched off due to a current fault, the residual current (I R ) flowing through the arresters (9) of the assembly (3) is switched off by the mechanical switch (4). A capacitor (12) arranged parallel to mechanical switch (4) leads to passive resonance effects, which in turn induce current zero crossings in its arc. The current zero crossings allow to extinguish the arc reliably. The mechanical switch (4) can be an AC circuit breaker.
