How can I make a simscape representation of the simulink 'Universal Bridge'

I've got a model of a wind turbine that works using sim power systems. For work purposes I need to convert this model to an equivalent simscape representation. The electrical system and grid have all been represented as you can't really go wrong with impedances etc, but what I'm finding difficult is getting the DC/AC converter to work.
On the sim power systems model I have a universal bridge with following values:

witht the configuration looking like this:

My question is how can i replicate this using simscape IGBT'S that are connected like this:

I notice that in the IGBT simscape block, the parameter Vth affects the quality of the AC side.

Hi, I think the closest block to the Universal Bridge in the electrical library is https://fr.mathworks.com/help/sps/ref/converterthreephase.html
You still have to find the threshold voltage (from component's datasheet if available, if not you can maybe check some examples), but you have almost all the other parameters so worst case scenario you can tune the threshold voltage according to what you wait from the output. Hope that helped.
