[Scilab-users] Faster PWM signal

@Serge: Thank you for the idea!
I found my problem for running faster. It turns out the slope of the triangle waveform is independent of the period so I had to apply a greater gain for the sawtooth for it to cross zero. Now I am running at 50kHz.
Thanks,
Michael Greenish

Try with lower solver tolerances with the Simulate/Confiure menu.

Hello,
I am modeling an electrical circuit. I have a voltage across an inductor being switched on the ground side. I am generating a pwm using a sawtooth genartor as shown by the attached image. In my circuit, my PWM switches at 50kHz. When if I set the sawtooth generator period to > 0.025, the results look as expected on the graphs. If the sawtooth generate period is < 0.025, the results are flat; the system can't seem to calculate at that interval. The period on the timer attached to the scope is 0.0001.
I am only at 25ms, I need to get to 0.02 ms to match my real-life circuit. Is there a limit of the system I am running into or do I have a parameter wrong?
Thanks,
Mike Greenish
