Hello.
My project is multi level inverter (diode clamped).
The schematic and the required operation is in the attachment itself.
The switching logic is fine. I got the output in the matlab too. (attachment 2&3).
My question is:
I know how to work with a 4 switch H-bridge. The high side mosfets need a different, dedicated ground. I have desgined some H-bridges using opto couplers or IR2110.
Iam not satisfied with Using dedicated power supplies for each opto coupler. Of course its working good.
But now, there are totally 7 mosfets require dedicated grounds. Is there any simple solution for this.
