Control signals are the same regardless of current and voltage rating so the
same chip for example a MCU or FPGA could be used for signal generation
regardless of size which is the reason why I want them as separate modules with
or without the control logic. The second reason is inverter bridge
Most of this discussion is past my knowledge level
but this may be easy to build ( not a module but few parts )
and 250w to 2kw and fairly high voltage

Yes it is except EMC problems. This module have three half bridges. I used two
half bridges and four dicrete transistors instead. It works but would be
simpler to just buy this building block if available.
With direct access to the switches I will be able to implement better control
algorithm
I have not been able to find simple inverters or half bridges which is the
basic building block of an electric motor driver regardless of type or size. Do
anybody know about??
Currently I am developing these half bridges myself. It works great but it is
time consuming and the result is not the

They come very close and I have looked on them but I still have to make a
circuit board so I have chosen a driver from the same company but discrete
transistors for flexibility.
If Vss and COM are fully isolated I might reconsider again. I had planned to
put isolation barrier at ethernet
You don't mention voltage or current ratings. They are pretty relevant.
The bigger you go the more demanding the power circuit design becomes,
and the less likely you are to find pre-built all-in-one solutions.
