Hi, I develop a circuit using Simscape blocks. My input signal is developed by simulink blocks, "random number + Matlab function block". I use the simulink-PS converter to join this signal to my circuit, but i can't. What is the problem? Thanks in advance.

Are you connecting the output of the Simulink->PS converter to a source block?

I recommend looking at demos to understand the difference between a physical signal output by the S->PS block and the physical connection between Simscape components.

For more specific help, add more details or an image of your model.

Simscape should be good for your problem.

The problem is that Simscape does not know if the signal coming from the S-PS is your desired current or voltage.

You need a block to specify that, pick one of those:

For the voltage sensor, it should connect, try to connect it a bit farther from the Capacitor port.

hi , direct connection between one or more physical signal converters found. Direct connections between physical signal converters is not currently supported.what's the problem?
