Figure 1: Topology of a SiC-MOSFET half-bridge with highlighted parasitic inductances

With the increasing spread of high-voltage power semiconductor components build with silicon carbide (SiC) technology, which operate at switching frequencies above 100 kHz, the requirements for their gate control are becoming more and more demanding. Besides the bipolar, positive and negative driving voltages fo
