What is the maximum rating of high voltage switch produced using series connected IGBTs for high power conversion?

We have the maximum rating of 6.5kV with 3kA switch this rating is not enough for high power conversion. So we are connecting discrete switches in series to achieve maximum rating high voltage switch.

Martin Schulz

Dear Mr. Imayavaramban,

as currently 6.5kV is the highest blocking voltage for industrial IGBT-modules and series connection is very rarely the best option, could you please add information about the apllication?

Wouldn't a multilevel approach be a more viable solution?
