Hey guys, I'm a new member to this forum, so I have no idea if this topic has arisen before. I have a project coming up where I need to hold off about 3000 volts using an SCR. A single device with this type of holdoff is really expensive, so I'm looking for an alternative solution. Years ago, I read (or heard of) someone putting two SCR's in series to achieve higher voltage rating. I believe it can be done, but I'm not really sure how to trigger two SCR's at the same time (isolation transformer, precise timing and Di/Dt and all that good stuff). Anyone out there with any experience in this application??? Thanks, Stan
