Hello - I just replied to your Thyristor query - but wanted to reach out. Feel free to contact me I am in this field, and work at this power level for Thyristors, IGBT and SiC MOSFET.... I can just discuss / review if you wish. I do work for one of the manufacturers, but I am sure this is not any impact to my personal business - I can just discuss and not really try to sell you anything.
