I am designing the single phase inverter. The input of the inverter is around 35 Vdc, and output is 24 Vac. The output currents will be below 1A. I control the inverter with F280039C from TI on a daughter card. I have multiple ADC signals coming from inverter to microcontroller via op-amps. (currents and voltages sensing from inputs and outputs).
I was thinking to design it with separated power ground and control ground and joining together two grounds by ferrite beads. I highly rely on single-phase inverter design from TI. Then I start to reading about separation of grounds, and now I am not sure is it a good approach. I read some articles, for example on altium.com, but they mostly divide approaches to isolated (with transformer) and non-isolated designs. The inverter case is a bit different. Should I stay with approach from TI and use just ferrite beads or create a single ground plane and just separate components on the board?
