Simscape Electrical conversion to Simulink and back

Hello,

I have used Simulink for a long time but I am new to Simscape. I am trying to build a model of a DC motor controlled using a H Bridge. Just to try something out, I want to connect the BRK port of the H Bridge to a signal coming from Simulink, using the Simulink-PS convertor block. But I am unable to do so as you can see in the attached picture.

Is this not the right way to connect Simulink to PS?

Thanks,

Anish

BRK is an electrical signal, so it needs to come out of a voltage source instead of directly from a Simulink-PS Converter.

Try adding a Controlled Voltage Source between REF and BRK, and connect your Physical Signal to the control node.
