I cant generate a square wave to control the gate of Transistor
From what I see the problem is in the MATLAB function blocks. The output is 1x100 but should be a scalar.

Error in port widths or dimensions. Invalid dimension has been specified for input port 1 of 'DFIG_SMC_new/PWM Generator (Multilevel)2/Model/Relational Operator1'.
Uref input has wrong dimension and therefore the error. Check dimension of Uref.
