Experts I am facing time step too small error.

[Altamash91]

Experts,

I had a problem of time step too small error in multisim circuit. I am working on the circuit of single phase induction motor control by triac. I had tried so many methods but still can't find its solution. I have attched my circuit file. Kindly rectify it and suggest me to what to do? I am waiting anxiously for the reply.

Thanks

Hi,

I replaced the following parts:

opamp - The one you selected may not work with a single supply

 resistors/potentiometer - you used the rated models which can cause simulation error. I replaced them with the ideal model

Triac - the one you select doesn't have a model

not sure what you AND gate is for as one input is opened, I connected it to the timer
