Comparison of LCI versus VSI Technology: Myths and Truth ...
The other VSI type can go up to 11 kV but is limited to much lower power. I wonder why the other VSi type is actually stated in the summary table as it is again quite misleading. Of course, [2] is already few years old and the technology evolved. There are nowadays VSI platforms for higher power and higher output voltages available on the market.
