How can I connect a transformer to a IGBT in simulink?

Hi.

I'm trying to simulate cascaded H-bridge multilevel inverters in simulink.

The problem is, I need to connect a transformer between the stages as shown here:

But I still can't found a block that would work. All I try don't connect and just show the red dotted line like this:

That transformer is under Simscape > SimPowerSystems also like the IGBT elements.

I also would need to connect a R-L load, then a single phase induction motor across a n points. I read about some incompatibilities with blocks from simulink and simscape and type of signals but still can't find a solution.

Any help would be appreciated, thank you.

Hi,

i guess you are mixing 2 different physical Domains - try this:

ideal transformer

or

linear transformer.

To link between Simscape Blocks from Simscape™ Electrical™ Specialized Power Systems and Simscape electrical circuits you might need this link:
