Why cannot I connect the controlled voltage source to a 3-phase inverter with Simscape blocks?

Hi,

I'm having problems to change a conventional AC source to a controlled voltage source in my system. The conventional AC source doesn't accept a variable amplitude and frequency (or at least I couldn't). The new variable voltage for the phase A is attached below:

However when I try to connect this new voltage source between neutral point and phase A inductance, it is not possible and a red dashed line is plotted. What do I need to connect? I need a interface block?

Thanks

Borja

The blocks are from different technologies. The circuit is implemented using Simscape technology and the Controlled Voltage Source is from Specialized Power Systems technology. There is not direct way of connecting the two technologies. Best is to use a single technology, there are equivalent blocks that would enable you to do this in either technology.

The following voltage source blocks are in parallel, or are connected in a loop(s) of voltage sources:model_08/Three-PhaseProgrammableVoltage Sourcemodel_08/Three-PhaseProgrammable

Above was the error message I recieved after trying to connect the Programmable Three Phase Source to Three Phase Source supplying the load.

This was the error message. How can I solve it.
