Hi sir I made your circuit but out put not stable I have set output 14V but just 3A load output drop 14V to 10.5 Please help me

[@electronic7979]

Nice electronic circuit

[@mr.gaurav4545]

I made it after watching this video 3 times Thank you very much for your help

Hello sir, good jon for this project, I want to ask, what if the input of the solar panel is only 18V, what components need to be changed for the MPPT system for charging the 12V battery?

[@LongTechnical]

Don't need to change anything bro

[@arnoldysugondoputra1405]

but when I tried this circuit with the same value it couldn't work with 18V solar input value sirr

[@arnoldysugondoputra1405]

I want to try this circuit for a solar panel to charge a 12v battery sir

What about significantly higher output voltages? I want 130v from a input voltage of 150v

[@yuribiktop6595]

nice work without pulse transformer. Can the variable be adjusted to 15v output?

I want to make 48v output. How can I do that what I need to change in this circuit? I already completed this circuit. Now I need 48v output.

Using field effects igbt rated for high frequency dc to dc converter for better temperature control using regulator mosfet with cause heating to 80 % with very little loed

[@salmanahmed9464]

Hi friend i made your circuit but i noticed that output voltages are not stable moving up & down meaning 48v input giving output voltage jump from 44v to 22v why ??not stable second thing when you give 60v input ic 3845 will give very high voltage at mosfet gate that will damage the mosfet why no protection i use irf4110 please replay thanks and good work .

[@LongTechnical]

Max ouput 24V bro. Because it will damage for UC3845

[@salmanahmed1600]

Thanks it works with only 24v

Can you make 24V to 12V with 5A current dc to dc buck converter

[@LongTechnical]

Just buy bro. Around 1 usd

excellent work Boss. Can you design 400v to 12v mppt? please give information

[@genalphalyrics8729]

So what would happen if i feed it with 12v at the input?

[@LongTechnical]

It just run from 20V to 120V. With 12V input you need 12V external supply for ic

[@genalphalyrics8729]

could we have something similar with a variable input rating say 20 to 120v dc. Great work...

[@Heliarc91]

Hi. Is it possible to modify this or to make it accept 1000+v dc and buck down to 12v??? I know voltage is high but wondering if you could convert it with high voltage rated transistors and caps. I assume it just bucks current intermittently as it is being used to reduce? How efficient is it?

[@samcreation9225]

For that you have to make flyback circuit
