Tool/software:
In the new document, it is mentioned that we could choose to place the MCU ground on either: Mid point DC-link, negative DC-link, or grid GND. There is possible voltage fluctuation on the mid point of the DC link. Does it affect the MCU?
For 3P3W grid input, how do I connect the mid point DC-link? If I want to place my MCU GND on the mid point DC link.
