It's just a bit over $100 in parts (including the price of the board). There are 2 drivers/power supplies. Here's a picture of it:
It drives to +15v and down to around -8v for shutoff.
This would work well for mosfets too. It might be a better choice for the SR controller, due to the absurdly awesome drivers. |
Well you took my idea. LOL ask for driver suggestions from me and then take it to the extreme. One thing though, These modules are only rated to run 600V modules to 600A and 1200V modules to 1400A. Testing will have to be done to make sure they are not overloaded with larger modules.

They cost more and you will not want to use them for the low frequency modules.
These are the ones I plan to use as there really is not any other suitable driver out there for high input capicitance modules. I just have not had the money to buy 2 for testing.
