Very very informative and knowledgeable vedeo. No body can't teach and explain in this way except you. Thank u very much. God bless you and entire family. Thank u again,
Thank you for your valuable service! Great job explaining! I went from knowing NOTHING about power electronics and SMPS's, to being able to at least diagnose where the problem is. Almost ALL electronics in the world use SMPS's now, so that makes this one of the most practical electronic channels on RU-vid. Especially now, with shortages in the world, a broken machine could cost $$$$ each hour it's down! Can't just throw it all in the garbage like the old days! Have a great day sir!
best regards and special thanks for your valuable words yes you are right, these days the SMPS is the main item in modern electronics and it is a biggest headache. so that is the reason still my focus is on power supplies. other all digital electronics and analog electronics is very simple. that can be diagnosed very simply and easily
Thank you for the comparisons , something I would of liked to done myself but you save me the time and helped me understand the differences between them. 👍
Sir kindly E-Vehicle Charger, Controller ki ek series banaye.. We need sir.. Because knowledge given by ur end is very nice not comparable not beatable. We always oblivious for that. 🙏🙏🇮🇳🇮🇳
Thank for your time and effort to explain the most important information If you dont mind I want to ask about mosfet drived by utc3842 sometimes we find diode and low resistance in parallel to feed signal to mosfet gate the question is how that work and what the benefit of that Thank you again
So informative Sir, as always something nice to learn. Thank you. So I guess it's best to replace with the same types, instead of modifying any circuit.
Assalamualaikum bhaiya.... Bhaiya I'm very confused in positive , negative and ground what is defference amoung it.....I've been failed to find answer on whole RU-vid..... Bhaiya if you read this comment plz plz Clear all this doubt..... Like what is defference..... +12, -12, and what is ground.....??? Q¹....What potential deference will be between +12 and ground , -12 and ground, +12 and -12......? Plz plz plz plz make a long videos with deep detail. ....🙏🙏🙏🙏🙏 ... . . . .. God bless u
Why would you use a UC3844 instead of a UC3842? its half frequency, half duty, but can't you just use different cap/resistor values to halve the frequency of the UC3842 while maintaining it's 100% duty adjustment?
Uc3842-43-44-45 In these series witch one ic is best for buck converter and pls make next video on buck converter with one of this ic thanks in advance
🙌Hello Sir! i'm learning a lot from you, thank you! Sir, can you please explain the E247691 (EAX64604501) LG TV POWER SUPPLY? It has 3 volt but no other output(12v, 24v..) even turned on the switch. What could be the reason? Please!
good afternoon sir, I just tried make a simple 17vdc power supply for UC3842, by using resistor 220k/3watt and zener 17v/5watt (IN5354B), and capasitor 220uf/35v, taken directly from the main power outlet and change it to vdc (about 310 vdc), but it does not work well, the voltage at the zener point is not stable, but if not connected to the UC3842 then it is fine, stable at about 18.1 vdc, please advise me how to make it stable? thanks a lot sir, cheers.
Slmz, Please do a video on short circuits, I understand electronic short circuits, to a certain level, but it becomes tricky with smd components especially with capacitors. Are all caps one side ground, and how much resistance or voltage drop exactly is a short. Some ppl test in diode mode, red on ground, some test diode mode black on ground, some test in resistance mode? Which is the correct method?
Olá amigo sou do Brasil! Fiz um conversor bucha boost aqui está funcionando bem com a entrada de 36v saída de 18v como faço para alimentar mais a tenção na saída?
Dear Sir ..Thank you very much for your valuable explanations. Sir.. Can i replace UC2844 with UC3844? One of VFD power supply with UC2844. But our market not available 2844. Then I was replace 3844 but now output on and off only.
ola eu montei um conversor buck aqui so que o marximo de tensão que eu consegui na saida foi de 20v ja mudei a frequência e nada! poderia me dar uma dica para alimentar a tensão de 20v para ate 30v na saida
