I am working out a 1 phase Multilevel Cascaded converter using a 3-Phase Back-to-Back Inverter Research Board converter. But I cannot use a single board to design this. Because both the inverter on board has common ground. So is there any way I can separate both the converters ground.
This is very important to me. The alternative is I have to use two separate board to design this which is a lot more cost. So I am definitely looking for a positive answer.
Thank you in advance.
