I would be most grateful if you could comment on the following. The attached is a circuit to charge or discharge a capacitor via a 120R resistor. The capacitor is then discharged through a low resistance route not included in the diagram.
There are three IGBT's in the circuit the charge and discharge are medium current and the 2nd discharge IGBT is a higher current to take the short circuit rush.
What concerns me is how to drive the devices. I have included TLP127 photoisolators but I am wondering about the grounding.
Could anyone comment.
