| Mar 27, 2023 at 18:23 | comment | added | PStechPaul | I tried that and for some reason was unable to achieve CCM. Maybe I had the wrong values, but I think it's due to some peculiarities in the simulator. It seemed to work in another answer. There i think I was able to get the voltage to PWM device working properly. | |

(to achieve continuous conduction mode increase frequency, inductance (current down), or duty cycle(current up.)) What is the difference to using a square generator where now there is triangle+comparator?
