Nice work ! Keep it up !
Awesome project dear 😀👌
Nice electronic circuit
Exelente sensei ideal para amplificador 200w
Your awesome! keep doing cool electronic stuf!
Nice work ! Keep it up !👍👍👍👍✔✔✔✔✔✔
Very good, friend!
Tks...
thank bro
Good work sir
I made it after watching this video 3 times
Thank you very much for your help
The ground is not connected in the 5 the pin of ic how its work
i followed his pcb but failed. please help me?
very nice , thank you very much
Thank bro
nice work without pulse transformer. Can the variable be adjusted to 15v output?
Great 👍
Thank bro
Amazing work.. by the way what is the use of inductor
excellent work Boss. Can you design 400v to 12v mppt? please give information
What about significantly higher output voltages?
I want 130v from a input voltage of 150v
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
Components values not visible in Eagle 6.0 software when opened you buck converter schematic.
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.
The 5 the pin of the ic not connected to the ground then how it will turn on
Only 0.1% RUclipsrs share actual schematic. That's the truth.
Super
thank bro
👍👍
What is the value of a 3 watt resistor? Looking at the color, it shouldn't be 1k and 25k for sure.
hi, can i put this mppt in an epever pwm to charge the battery, good job
Very nic bro
Thank bro
Bác cho em hỏi nếu muốn cho xuống 48v có được không bác em làm chỉ chỉnh được 28v max em muốn sạc bình 48v bác à
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
can i put these in place, mosft Irfp4668 ,schottky Mbr7030wt
could we have something similar with a variable input rating say 20 to 120v dc. Great work...
Solar panel
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?
Don't need to change anything bro
but when I tried this circuit with the same value it couldn't work with 18V solar input value sirr
I want to try this circuit for a solar panel to charge a 12v battery sir
@@arnoldysugondoputra1405điện áp đầu vào phải lớn hơn điện áp đầu ra ~9V vì UC3843 được treo lơ lửng phía cực dương
Can I get the specs for the inductor core and a link where to buy it🙏🏽
sorry sir, is it possible to input 60v and output 12v?
Helo Sir.. what is max output voltage? can that reach 42V ??
mạch hoạt động không ổn định, phía chân 1 của ic bị nhiễu rất nhiều
Nice bro 🇧🇩🇧🇩
Thank bro
He used ne555 ?
Can I use uc3843 instead of uc4845?
Sao e chỉnh áp ra ko được ah ... muốn chỉnh áp ra phải chỉnh R cấp nguồn nuôi ic là sao ah
Can you do it with 220 volt
Great work super sir
Try to do one buck boost converter DC to dc
OK next time bro
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 .
Max ouput 24V bro. Because it will damage for UC3845
Thanks it works with only 24v
Can you make 24V to 12V with 5A current dc to dc buck converter
Just buy bro. Around 1 usd
What is its max Amps ?
CAN yo make a step up converter from 12v to 50-200v at maximum 300maps
Already have that video in my channel. Checking it
@@LongTechnical send me a link please
Sir Input voltage range and Output voltage range please ....
So what would happen if i feed it with 12v at the input?
It just run from 20V to 120V. With 12V input you need 12V external supply for ic
@@LongTechnical okay thank you....and please make a video on how you can turn a microwave oven transformer into a power supply...i heard that thing can output 2.1 kv
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?
For that you have to make flyback circuit
Can i buy it from you?
File is not downloading?
Berapa harganya ,kalo beli sudah jadi?
what power? Can you make me power supply ac dc 46 volt 30 ampere with sort protection, over protection, stabilizer protection?
Already have that video in my channel. Checking it
Hello sir how are you
Sir, what is operating frequency.
30khz bro
possible to make it for 24V/36V/48V/60V output from 120V input?
Only one of them
You'll need to you multiple buck converter for each voltage
please pcb price
