I know for this we need ps-simulink converter but still i can not connect schmitt trigger to ps-simulink converter to display output, connection problem with red dotted line. Give me suggestion to get out of this.

You'd need to connect a Voltage Sensor between the electrical network and the PS-Simulink Converter.

Thank you for your response here i got an error when i try to simulate and simulation is terminated with an error. Actually i need to generate pulse width modulation with variable DC voltage.
Here is the error
Tie variable 'schmitt.Comparator1.n.v' (Voltage) to a definite value, for example by connecting an appropriate domain reference block.
Equations of one or more components may be dependent or inconsistent. This can cause problems in transient initialization. Here is the set of components involved: 'schmitt/Comparator' Equation location is: 'C:/Program Files (x86)/toolbox/physmod/elec/elec/+elec/+integrated_circuits/comparator_eqn.sscp' (no line number info)
'schmitt/Comparator1' Equation location is: 'C:/Program Files (x86)/toolbox/physmod/elec/elec/+elec/+integrated_circuits/comparator_eqn.sscp' (no line number info)
