I have set up a boost converter with a regulator in LTspice, but I get a lower voltage at the output than at the input. What could be the reason?

Look at your compensator: 1mR along with 1000uF. Do you think that these values are normal? – Rohat Kılıç Jan 04 '22 at 08:39

Thank you for your answer, this is my problem, how can i dimension that? – Sarah Jan 04 '22 at 08:43

when I change the values my output voltage stays the same – Sarah Jan 04 '22 at 08:48

What happens if you remove them? – Rohat Kılıç Jan 04 '22 at 09:35

Try running it 'manually' first. Put a fixed pulse waveform into the switch, and see what happens. Find out what the various parts do open loop before you close the loop and complicate things. – Neil_UK Jan 04 '22 at 09:38

If I delete the capacitor and the resistor in my PI regulator, then I get 24 V at the output as desired, for this I also had to increase the resistance at the output to R1 = 10G. What I want to achieve: to simulate a boost converter with a constant output voltage, that's what I built this regulator for, but the knowledge from my lecture and university was not enough for me, I don't know how to properly simulate the values, I work with LTspice – Sarah Jan 04 '22 at 11:03

I shared the new picture above again :) – Sarah Jan 04 '22 at 11:10
