Hi All
I need some help with my motor controller design. I have an NE555 output of 2.5ms or less pulse that needs to turn on an IGBT Gate. I need the circuit to be isolated from the NE555 circuitry. How can I use an Opto Isolator to do this? I have some IXDD614 drivers Ua7815 power Ics. also available is a power transformer output of 30VAC. the NE555 circuitry is using the other transformer output to get 15vdc. So the second transformer output I think will give me an isolated DC needed in the Opto output and driver circuitry.
Does anyone have a working schematic?
