Hello Ayoub,
you are using a block specifically designed to be the arm of a multi-level converter, It is not a standard full bridge architecture, so there are no ports accessable to the portion that you would use for the ac portion of the circuit. It only has the dc input. The easiest thing to do would be to build the topology yourself with individual devices (either igbts or mosfets, I would start with ideal ones).

Hello ayoub reffai,
In your model you need to connected dc supply for converting DC to AC
you have used only voltage and current measurement block

Hi: The PWM output is a gate pulse and is given to the G input of inverter through a four pulse gate multiplexer. The + and - terminals of inverter should be connected to a DC voltage source. Thanks.
