{1133} Ebike / Electric Bike Battery Charger Repair

in this video {1133} 48V Ebike / Electric Bike Battery Charger Repair, i demonstrated how to repair LNYAQA LY88-001 T/TCDZ0001-2019 it is 48V12AH battery charger, it is not powering on. it is using UC3842 ic as smps controller. in secondary side it is using LY03 and LM38 IC as battery management system

You should have changed the 4th bridge rectifier diode also. Since all other diodes and mosfet are short circuited and whatever caused that to happen such as a high voltage spike/high inrush current must have flown through the 4th diode also and must have barely survived from becoming short. There still a high chance that the diode will eventually fail when compared with the other 3 diodes

[@shyamsuresh1723]

I know you are doing this for test and educational purposes and you are way more experienced than i am. You probably already know what i mean but i just wanted to point that out

[@HaseebElectronics]

yes. i agree with you
that is great suggestion.

[@antiamperak]

​@@shyamsuresh1723Naprostý souhlas je i dokázáno že i poslední dioda je poškozena, tento stav je velmi častý dochází k poškození PN přechodu a dioda v závěrném směru ztrácí odolnost proti průrazu. Proč to teď dioda vydržela je jednoduchá odpověď zdroj byl nezatížený a navíc byl připojen přes omezení proudu ( žárovka)

السلام عليك يا استاذنا الفاضل بارك الله فيك على المعلومات القيمة والشروحات المتميزة والنصاءح الهادفة والتوجيهات اخوك خالد من المغرب الدار البيضاء متعلم مبتدىء

[@user-xf7um3st2u]

sir, thank you for uploading, I already have a reference for repairing my ebike charger

[@rajkhumar001]

Awesome sir🎉

[@antiamperak]

Poškozené jsou všechny čtyři diody je dobré je vyměnit všechny nebude dlouho trvat a tento zdroj bude opět na opravě nedávno jsem o této problematice natočil video na můj kanál. Dioda sice vypadá že je v pořádku ale její průrazné napětí se sníží až na třetinu. Při mém testu dioda která měla vydržet 1kV zvládla pouze 350V tudíž by netrvalo dlouho a došlo by k poškození i této diody. Multimetr nedokáže měřit takto vysokým napětím tak proto se nedá zjistit poškození v závěrném směru. Mám rád tvá videa hodně mě naučila pokračuj ve své práci a zkus změřit tu funkční diodu a prosím neber tento komentář špatně je to pouze rada. Děkuji

[@ComputerExpert1]

Thanks for sharing Sir

[@German_byte]

Brilliant work

[@sandeepmane2983]

1 Number work 👌

[@khanlalavlogs]

Excellent sharing....

[@Solder_it]

Very good video prof and thanks for sharing, i have one question, how can i know if that sound is normal or not? Humming sound

[@user-vd9xz4ps2q]

👍👍👍👍Salam Alaikum

[@pascalphase2556]

Great job ! But how do you know the value of the dead zener diode ?

[@fuppup]

Thx a lot🤝

[@palwindersandhu2031]

Thanks very much dear .....

[@prkacro]

Thanks ..

[@jcsudeshchannel8224]

😊❤ good

[@mehranmohamad6924]

hi good time. how did yiu find out the type of zener diode in the mosfet gate drive and how did you choose a similar type of diode?

[@HaseebElectronics]

almost all gate drives are protected by a simple fast switching signal diode like 1N4148. so that the PWM controller ic will not be effected by negative transients generated by mosfet switching and gate discharging

[@toons7076]

What is the input resistance in good circuit

[@MrDricooh]

Where to buy that soldering

[@MohsenSedighian]

Hi. Mr. Haseeb. I'm from Iran . I've a switching power supply that it's switching IC has been exploded. I would be glad if you can help me to find the number of this IC. Help me if you can . I've just two picture of it's board and i donot how should i send it to you . let me know the way.
best regards
m.sedighian.

[@TheMrjogas]

Hi where you purchase hc42ym

[@yandrapuvenkatesh6732]

What is the number of damaed pwm ic and replace ic number. Tellme sir please

[@mohammadkhalid6886]

How do you discharge the capacitor,,, what is in a transparent white box,,, Jazakallahu khairah

[@German_byte]

Watch video number 1114 to see how our teacher discharges capacitor.

arıza yapan diyotların yerine başka hangi numaralı diyotları kullanabiliriz. neden? farklı diyot kullanılırsa ne olur?

[@huseyinogan4971]

Akım değerlerinin aynı ya da yakın olması lazım.

[@iosifferencz5432]

Acolo cauza este "greseala proiectare" poate si intenționata pentru ca sa mai cumperi si producat +lant comecianti sa aibe de lucru..
la fel si Dvsțra .
Sunt solutii ca un produs sa tina multi ani dar ne mai exista interes😢.
