Hello, I run simulink to see the voltage graph of AC source but how it shows like this? Do I set some parameters wrong? AC voltage peak value is set at 100v others parameters are left as default.

Look at sample time in AC Voltage source block.. You may need to replace with your required sample time.

Sample time can not be 1000. If the freq of the sine wave is 60Hz, Then you require sampling freq of atleast 300Hz i.e sampling time of 3.33 mS.

Moreover when you change the sampling time, it is as good as discrete system.
