Hi Mark - sure.
the BOM is:
* A3120 IGBT driver isolated opto-driver - from Digikey 751-1475-1-ND $2.31 1 $2.31
* DC/DC 2W 12V->+-15V - from Digikey 102-2096-ND $5.96 1 $5.96
* 18V zener - from Digikey 1N5355BGOS-ND $0.37 2 $0.74
* 50uF 25V el caps
* 10R 1-2W gate resistor
* 1k 1/8w resistor
* 10k 1/8w resistor
As I mentioned, these parts are ok to drive a 50nF IGBT at up to 10-16kHz.
Let me know if you have any questions or would like me to order some more copies when I make them for my controller...
Thanks,
Valery.
