This is great, especially your clear explanation regarding how robust the protection on these reasonably priced boards can be. I especially appreciate how you took the time to explain how you induced a failure that the onboard protections more likely would have prevented. Great stuff!- As usual🤙

Just wow!! This is simply incredible!! ❤❤ I started watching this video, and I simply couldn't stop. I wish more content electronics content creators make videos like this. Very well explained. You are such a good teacher. Thanks for the video. I learned a lot!

Great, finally we have now repair video.

BTW, I’d way rather you “over-explain” concepts than the opposite. We can always re-review any concepts you present at our leisure, as your method of instruction is so clear, concise and well presented. You don’t over-explain anything imho, I reckon you present enough information to glean practical working knowledge of the topics/devices/components you cover. Jah’s blessings upon you my braddah!

Great sir❤❤❤❤❤

great video

SUPER!!!!

Great video! I fixed my one too last year. In my case the irfp4110 was a fake one. I opened it up and the silicon die was tiny. Can you open your one? and show us how big the die is.

Love it, such useful info thanks

You are right, these are very expensive in our country. I live in Bangladesh.

A lot of work need to making the video great work bro. Need one suggestion about input voltage I have booster 1500 watt with input voltage capacitor of 63 volt and 470 uF , if I will change all the four capacitors with value from 63V to 100V volt input section then if it can burn or not or work normally if I apply 90-volt input.

thank you so much for vid❤❤

A quick comment on this style of boost converter-It would be wise to ensure that the MOSFETS/switches on the bottom of the board are making contact with the heat sink. Upon inspection, before applying power to my sample, I noticed that, while all the requisite silicone heat spreaders were installed, NOT A SINGLE DEVICE was actually contacting the heat sink. Glad I checked, I prefer to keep the magic smoke contained😎

11:50 Это мосфет на 80а, скорее служит от переполюсовки, если вдруг при подключении перепутают плюс с минусом. Это очень хорошо, такое редко встретишь в приборах

i am a international tradesman and these converters cost around $5 if you buy mass, with 30 day sea shipping, total would be around $7. but youll need to buy 20+.

Dam That's my point bro 25 dollar or more is really expensive to spend I live in india i do really find it bit expensive tho i like u really thought about money

You can share the 3D file to print it, the one at the base of the step up module?

I think the input mosfet job is to cut out voltage if the undervoltage power detected

You by pass the protection so as to measure max power and breaking point

why you didn't dig deeper on the 2nd failure? It was TL494 IC voltage supply capacitor that exploded. It is rated 25V on my board, interesting why it failed in such a fashion for you.
