I Modified My 400W Boost Converter to Buck-Boost

[@rofeiga789]

You are a genius. I love your work from the bottom of my heart.❤❤❤

[@Electronic_For_You]

Thanks bro 😊

[@thiruchelvamselvaratnam2252]

You are GREAT. Can you please show me and your viewer the circuit diagram before and after the modification . THANK YOU.

[@Electronic_For_You]

It's very simple modification doesn't need diagram

[@earlyadapter643]

Its nice to build stuff that works by intuition and without a circuit diagram, but i did make a circuit diagram for what you built and i can tell you that it is not a buck-boost at all, but a flyback converter with isolation. The extra diode and its resistor is the snubber network to absorb the energy stored in the stray inductance of the primary coil and protect the mosfet.

[@Electronic_For_You]

You are right, 👍

[@vitalyne...]

@@Electronic_For_You 1. The resistor in the damper circuit heats up catastrophically. I put 1k at 5W, but it's also on the edge... What could be the reason? Maybe 1k is too much? Or, on the contrary, too little? 2. I conducted an experiment: 35V/6.18A at the input, 44.58V/4A at the output. The efficiency was 82.4%... But more often 78-80%, no higher. At the same time, the choke and transistor heat up very much. I wound the choke on a larger core with a diameter of 33mm and a 2x1.35mm wire I think if the load currents are not higher than 2-3A, you can still put up with overheating... if the currents are higher, then something will definitely burn out... By the way, I put radiators on the diode and transistor that are about 10 times larger than the original ones (but they don't help much)...

[@Electronic_For_You]

Try using a Higher Value load resistor like 4.7K , and You can try changing the MOSFET with a more powerful one and also diode !

[@msnepaliman]

You did not test all conditions to confirm. Can we get 1.5V from 12V input?

[@ReppandGembelNarzis]

Bisa tidak kalo modul Xl4015 di buat step up down seperti itu,kalau bisa tolong buatin vidionya

[@Electronic_For_You]

No , XL4015 is a buck converter, You need a boost converter

[@jualanled5563]

Can you send a diagram, so I don't assemble it wrong? Is this like flyback mode?

[@Electronic_For_You]

I don't have a diagram really sorry, it came to mind and i made it , hahahah BTW , you can follow the Flyback circuit diagram it works the same , and it's also clear in the video what i did !

[@Electronic_For_You]

Before turning it on , be sure to use a Low power Input source like 12V and 1A only, in case someone is wrong it doesn't blow up , Good Luck :-)

[@jualanled5563]

@@Electronic_For_You I've tried it ( with boost dc 150W) , input DC 12V but buck mode low voltage at 9V, can't down to 3V to minimum of voltage,? have i re-turn /modify 1:1 to 2:1 of the wire ?

[@Electronic_For_You]

I think it's because there are some resistive dividers for Voltage feedback and these converters are made for Boost mode so minimum input voltage should be 9V To Work well with the ic ,

[@subhrapatnaik8326]

Hello the efficiency is too low about 75%. Have tried both boost and buck. Could you please help me with efficiency. Atleast i am expecting about 80-85%

[@ayyhmed]

@@gregjones3660 okay

[@MichaelHuwe]

I tried it but it failed. As soon as the circuit tries to start switching current rises up to current limitation and the transistor heats up. No output voltage. I'm not sure whether the coil is wrapped correctly. I think the idea is to have a primary and a secondary coil with the same number of winding, right? It's hard so see on the video.

[@Electronic_For_You]

Yeas , Make a transformer with 1:1 ratio and connect as shown

[@RBL-b1u]

can I create a video for 300w 9A buck converter, because my other side of MOSFET is burn thanks.

[@Electronic_For_You]

Try changing the MOSFET

[@onyekaezeagha4936]

Can I used this as constant current constant voltage battery charger

[@Electronic_For_You]

Yes, You can, but it's better to use a buck converter with CC-CV function

[@golammustafa662]

Bro the copper wire, is it normal copper wire or coil wire? I mean insulated copper wire?

[@Electronic_For_You]

Insulated copper wire

[@suddam2010]

Hi dear I have one like this, but I want to make it control the voltage coming out from zero (0). Can you tell me how to do that? Please answer me

[@Electronic_For_You]

Sorry, i think it has some kind of protection circuit, so voltage cannot be lowered than 11V.

[@MichaelHuwe]

Finally I got it to run. It does exactly what you show but I'm still unhappy with the heat it produces. I hoped your modification will reduce switching losses. Maybe you like to advise another possible modification I use. By adding a few resistors I created a static MPPT solar battery charger with this boost converter. Therefore I used the two error comparators for input and output voltage (instead of output current). Setting the output limiter to the battery-full-voltage will provide a battery charger that stops when the battery voltage reaches the limit. The input voltage comparator will pull your input voltage down to the MPPT of your solar panel by increasing output current until the MPPT is reached. It runs fine with a 33V or 44V MPPT PV-Module charging a 16S LiFePO4 battery up to a limit of ~57V.

[@Electronic_For_You]

Well-done 👍🏻 If it produces heat , then i recommend increasing the winding turns! In my case it doesn't produce heat 🤔 see if it's overloaded? And i do not recommend increasing the voltage more than 45-50V !

Здравствуйте, вы увеличили напряжение больше 50 В? А ваше устройство все еще повышает напряжение? Я думаю, если напряжение слишком сильно увеличится, потенциометр выйдет из строя!
