Owing to the faster switching speed of silicon carbide devices further demands are put on the serialisation method. In this study, a cascaded series-connection method using only a single external gate signal is analysed in detail, guidelines to size the resistor–capacitor–diode-snubber are proposed and its applicability is experimentally demonstrated.
