Hi MonacoFranz,

The gate capacitance Cge is designed to be large enough to avoid parasitic turn-on effects.
This negates the need for additional gate capacitors.
IGBT7 T7 is designed for zero voltage turn-off.
Besides, the ratio of input capacitor is optimized to avoid parasitic turn-on.
Gate driver circuit can be simplified, which means there is no need to use active miller clamping or shunt path for miller current.
More details you can find here.
