How to set step time for using Repeating sequence to create high frequency triangular waveform
显示 更早的评论
I am simulating Buck converter fed DC motor .To create pulses(20 KHZ) I am using repeating sequence.When simulted under normal auto step mode,triangular waveform is not created.When I reduce the step size (10e-11),I can simulate.But the simulation takes longer time. How to solve this? Please help me all. Regards srinivasan

I added the tag simulink and the product Simulink to your question.

The frequency of your pulse signal is 20KHZ which means the period is 50us. If the "pulse signal" is actually a triangular waveform, I would say your step size should not be larger than 5us, that is 5e-6. Your current step size 10e-11 is too small. I would recommend using 1us or 2us. Or you can set up the maximum step size to be 5us.
