Connecting power to the hot side of the EiceDriver (Infineon) for mosfet transistors.

Hello,

There is a driver 1EDI30I12MFXUMA1 (Infineon, EiceDriver).

Connection diagram:

To power the drivers from the transistor side, I want to use an isolated DC/DC converter with a +15V output.
One converter for two drivers.
Since I have Full-Bridge, there will be two DC/DC converters.

The only thing I don't understand is how to connect the isolated ground from the DC / DC converter output? Does it need to be grounded to the minus of the power bus? Or how?

How I see it:

Question:

Is this the correct driver supply (high side) connection? Any more ideas? Can 1 DC/DC be used for two drivers?

Thank you!
