Is a 10 kV SiC MOSFET suitable for medium-voltage power conversion?

Simultaneously imposed challenges of high-voltage insulation, high d v /d t, high-switching frequency, fast protection, and thermal management associated with the adoption of 10 kV SiC MOSFET, often pose nearly insurmountable barriers to potential users, undoubtedly hindering their penetration in medium-voltage (MV) power conversion.

How to improve the insulation of a switchgear?

It is determined that the connection and the corner is most likely to occur insulation problem, which the electric field is 1.23 × 10 6 V/m and 1.72 × 10 5 V/m respectively. Polishing connection and the corner is a good way to improve the insulation of the new switchgear.

Can high-voltage switchgear improve the reliability and safety of power supply?

In order to improve the reliability and safety of power supply and reduce the failure rate of switchgear, this paper designs a novel high-voltage switchgear which is reliable and safe.

What is the model of high-voltage switchgear?

Overall model of new high-voltage switchgear. The busbars in the switchgear are tortuous and it is the focus of current-carrying loads so that its grid should be finely divided. While the shell of the switchgear has a large volume and does not require excessive fine division.

Does the insulation and temperature rise design of switchgear meet national standards?

In order to check whether the insulation and temperature rise design of the switchgear meets the requirements of national standards, a simulation model of electric field and temperature field is established. According to the results, optimized design of insulation and temperature rise was carried out. 2. New switchgear design

What is a 16 kV PCB-based DC-bus distributed capacitor array?

Ravi, L., Lin, X., Dong, D., Burgos, R. (2020). A 16 kV PCB-based DC-bus distributed capacitor array with integrated power-AC-terminal for 10 kV SiC MOSFET modules in medium-voltage inverter applications.
