Hi, I'm designing a Single Phase Energy Meter, and this are my requirements:
- Isolated Power Supply for MCU Unit (Microcontroller + Display)
- Use shunt as metering element.
I think of using a Flyback Power supply with two outputs, one for the MCU Unit and the other for the ADE7953, so I can keep the MCU unit isolated from the ADE7953 (because ADE reference has to be Phase).
Can you tell me if this design is correct? Is there another solution that adjust to my requirements?
What interface do you recommend to isolate communications between MCU and ADE7953?
