MATLAB: Voltage Sag Generator


I was making a circuit to generate voltage sag signal as shown in the image in the link below:
As you can see in the oscilloscope, there are two signals instead of one signal generated when I was trying to combine one sine wave signal with one step input. It is a product of a sine wave and a step input so supposed the answer should be only one signal. The mdl file can be downloaded here. Please advised. Much appreciated.

  • It's the step block that's generation the extra signal, I'm trying to find a fix for it, please wait
    A way to fix it is to put a demux block in the output of the Product block and a Add block to add the demux outputs together, hope this helps.
