How could we connect a 4 IGBT block to a DC voltage source?

We are trying to make a simple bridge IGBT inverter and connect it to a DC source and in parallel with 2 capacitors. We are having the problem that you could see in the image: we cannot connect the source and the capacitors to the IGBT block and we do not know why.

It is not working because you are trying to connect blocks from two different technologies, Simscape and Specialized Power Systems. It is better to use only one technology that meets your requirements. There are equivalent blocks in both technologies. I hope this helps.
