Please note:
The dead time has to be longer than the turn-off delay time of the IGBT in any case. This is to avoid that one IGBT
is turned on before the other one is not completely discharged. If the dead time is too short, the heat generated by
the short circuit current may destroy the module in the event of a short circuit in top or bottom arm.
The average output current is available at each output channel. It is not possible to interconnect the output
channels to achieve a higher average output current by neutralizing the locking function.
