| Dec 9, 2023 at 19:40 | comment | added | loa rifa | thanks for your response, I used a variable inductor at my college laboratory but I have a small 3mh inductor and always plug it into my circuit, and Arduino frequency is 10KHZ, but do you have an idea why I can't get boost mode from this circuit. | |
| Dec 9, 2023 at 19:17 | comment | added | bobflux | Depends on current and switching frequency, but for a 50W panel you're expecting 4A at least so a bunch of 10µF MLCCs at least... I see a 1mH inductor, that's a huge value, what inductor did you use? | |
| Dec 9, 2023 at 18:36 | comment | added | loa rifa | how much value for a capacitor is needed, my maximum input is 20v, what is your suggestion? | |
| Dec 9, 2023 at 16:20 | comment | added | bobflux | Can you post a picture of the board? Why no decoupling caps on the input? | |
