السلام عليكم ورحمة الله وبركاته. Cher Haseeb, je suis l'un de tes abonnés depuis le Maroc, et franchement je trouve tes vidéos assez éducative جزاكم الله خيرا , peut être ma question n'est pas lié au contenu de cette vidéo, mais j'ai pas trouver de moyen pour vous contacter, donc si je vous dérange pas ma question est concernant une alimentation SMPS de 60V 25A que j'ai acheté en occasion, après ouverture j'ai constaté que les IGBT 60N60FD1 en été grillé, je les changer et une fois branché au secteur, la led verte s'allume et la tension commence à peut près de 5V puis diminue jusqu'à attendre 0 ainsi que la led s'éteint. J'aimerais s'il vous plaît savoir ce que je devrai diagnostiquer pour la réparer. Merci beaucoup و جزاكم الله خيرا.
My brother, you are not calling me a professor. You are a doctor. Could you please make a video of the device that you use to remove electronic elements from the board of this device that resembles an iron? Your student is from Egypt.
welcome dear brother that is WELLER WR3M rework station. www.indiamart.com/proddetail/weller-wr3m-3-in-1-high-end-electronic-pcb-soldering-9437196497.html?pos=2&kwd=weller%20wr3m&tags=A||||8235.275|Price|product|||TS|rsf:gd-|-qr_nm:gd|res:RC4|com-cf:nl|ptrs:na|ktp:N0|mc:423081|stype:attr=1-br|cat:846|mtp:Brn|qry_typ:P|lang:en|wc:2|cs:8638|v=4|r=4
.Sir why igbt when i test in diode mode the reading is good but after sometime i test again and reading or the voltage drop is decrease.what is this means.does the igbt is short.please help me sir
The colors do not matter initially. This type of misinterpretation is very easy to solve simply by measuring the actual part with inexpensive multimeter set to ohms setting. Then look again at the colors and match it with the correct ones based on measurement of actual part.... basically use some brain cells to determine what it is rather than just looking at it and guessing.
most of the time it is used in curret measuremet circuit. if we bypass it, the circuit will work noramlly but the current limiting safety will be compromised. and the circuit will damage in any overload condition it is much important to not to bypass any safety
Each videos are excellent sir 💯❤
Thanks a lot for your feedback
Excellent thanks for sharing❤❤

That video is already done just a couple of weeks ago, go back a few videos and you will find several.....

Build an IGBT tester or buy it, the test is done with a 9 volt battery and a LED, search for "igbt tester circuit"
In my eyes the first band is red , not brown . is it brown friends ? if red its 2 ohm.

Is there any chance to bypass this resister sir????

@HaseebElectronics noted sir, Thank you.
