1. I agree, it is quite complicated to get a good voltage distribution across all MOSFETs during turn-on and turn-off. Furthermore 10 kV is high voltage and one needs to be extremely careful with such voltage levels, which can be deadly. – Ken Grimes.

First, improved voltage capability. The breakdown voltage of SiC SBDs is able to achieve around 1700 V, which is much higher than that of 200 V Si-based SBDs. Chips based on a SiC diode were able to obtain a breakdown voltage of about 20 kV, which is almost equivalent to that of a high-pressure Si stack. The breakdown voltage of SiC …

In the current paper, we propose a complete sizing of the power supply and we justify the choice of each component, notably the 10kV SiC MOSFETs and diodes, as presented in Section 3. The experimental setup, performance analysis, notably through a power balance, and results are discussed in Section 3 and Section 4 .
