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.<br></div><div id="yui_3_16_0_1_1444926980224_2856" dir="ltr"><br></div><div id="yui_3_16_0_1_1444926980224_2834" dir="ltr">I am only at 25ms, I need to get to 0.02 ms to match my real-life circuit.
