Faster simulation

01:07:00

Can I make my simulation go faster? I want to see the final voltage but it won't allow me to go faster.

10MHz boost with 10uH coil and 90:10 pulse pause ratio is a little unrealistic. Also 10uF while you try it already that fast at 10MHz is much to big. I recommend 100kHz max and start with a PWM 50:50 so everything does run 100times fast then now. Transient simulation takes time, and sometimes they are useless to do. Better to start e.g. with a charged capacitor to not wait till its loaded.

Oh, thanks, I had set unrealistic values

Were do you got this high frequency from, 10MHz, just an idea? A boost converter can be split into two main phases. The charge phase of the coil and the discharge phase. If you charge 90% of time you need also some time to discharge it. Thats why 50:50 is the maximum point of power transfer for boost converter. For a buck its different it can be a full range 0:100 100:0 control.
