Hello guys,
I need to take some idea about how to design a power electronic PCB to measure the isolation between high voltage DC link and a floating EARTH or Chassis. Have a look to the next pic:
There are two possibilities or cases:
- CASE A: The positive side of the DC link is connected accidentally to EARTH.
- CASE B The negative side of the DC link is connected accidentally to EARTH.
I need to design an simple analogue solution to identify every CASE and to measure the current drive to EARTH. Any idea?
Thanks in advance.
