No power connections in your circuit - I presume its meant to be a half-H-bridge?
Why opto gate driver? High voltage? What voltage? Would a high voltage non-isolated gate
driver be usable?
high-voltage IGBTs' gates need 15V at 100's of mA drive typically, so you'll require a floating
15V supply for the high side driver anyway. Without high current gate drive the switching losses
with a DC-DC converter will be large.
There are some PV-output photo isolators but they tend to only output 8V or so and aren't high
current for rapid switching - basically good for low voltage MOSFET driving such as in SSRs.
A capacitance of 3300 is way beyond plausible. Please explain your circuit voltages, power level,
operating frequency and actual component values in proper units...
I choose to use a opto gate driver to protect the Arduino, because I am working with a "high capacitators". There is not a requeriment, use a opto gate driver.
Basically, my circuit has a PID Controller that will control the current in the inductor. Both of my capacitator has Max. Voltage of 3.8 V and Minimum 2.4 V.
