Your videos are always very infomative but your video quality is very poor, I think the ambient light should be increased for video and the camera quality should also be improved a bit
first of all. i am sorry for inconvenience secondly, i am really thankful for indicating a valuable point. and i will try my best to rectify these issue and will try my best to improve video quality please accept my best regards
@slotmachines756. This is also my observation I am already planning to improve video quality to 4k instead of hd video And am also idea to enhance light
Just put ur multimeter positive prob on switching mosfet and see if voltage is present and study then switching hot genrated If the voltage look like not have on mosfet switching is working
thank you for your valuable information. i have a one doubt. we have one ups in icu central monitor and it is not working . when i was open to check inside the ups. battery is 4v only but battery voltage is 12v. board looks like good no burning or defective component. when i connect ac power, cumming sound come inside transformer. after removing battery the cumming sound is disable. is there any ideal about this
Aslamoalakum gee Sir gee aap kesy Hein sub theek shukr alhamdulillah Sir gee ye btain ke aam labtop Supply se Kisi amplifier bke leay dual Supply kesy bna sakty hein plzz sir help me
Assalamualaikum Bhaiya.... Plz you can explain how does an ac non polar capacitor work in motor Or ceiling fan.... And why it changes its rotation direction When we interchange starting and running terminals..... I know how it works it's only superficial I wanna learn his deep working Plz plz explain in hindi with deep details.. If you read this comment... . . .. . .Have a nice day 💖💖💖
First of all, thank you. We follow you from distant lands. You are someone the world knows. But the sound quality of the video broadcast is very bad. Can't you get a quality microphone? I recommend you use a new and high-quality microphone.
Sir in flood lights thare is smps but it doesn't have optocoupler for voltage control. As per our led light requirements voltage auto adgest. So please explain how this smps auto adgest the voltage? And without optocoupler how it possible. please make video on this topic
Sir can you make one vidio on vfd reparing 972 vidio series make same all part wish explain stap by Stap all section testing processes thanx Same laptop reparing vidio series make all sections test step by Stap and all generation mother board power plan explain thanks in advance👍
SIR THANK U FOR THE VIDEO , IAM WARUNA FROM SRILANKA , SIR WTS THE IC DATA SHEET NUMBER THAT UR SHOWING IN THIS VIDEO , SIR AT THE FIRST STAGE WAS THE PWM IC PARTIALLY BIASED WHEN IT START SWITCHING ? IF SO CAN A PARTIALLY BIASED PWM IC CAN DRIVE A MOSFET ?AND ALSO SIR WHEN THE CAPACITOR IS CHARGING PWM IC DOESNT GET ITS VCC ISNT IT SIR , SO CAN U SHOW WTS THE DISCHARGING PATH OF THE CAPACITOR ? SIR IN THIS PWM IC IT TAKE FEED BACK NOT FROM SECONDARY SIDE BUT FROM PRIMARY SIDE OF SMPS WHY ? THANK U SIR PLZ EXPLAIN
@@HaseebElectronics sir I have recently developed SMPS 12v 10a working from 90v to 265v with uc3843. It is working good. From you only I gained sufficient knowledge. Thanks
جزاك الله كل خير أرجو أن تشرح طريقة عمل وإختبار LM358 المتواجدة في دوائرشحن البطاريات وألف شكر لمجهودك الرائع. وأرجوالله أن يكتب لك الأجر والثواب في نشر هذا العلم
Excellent as always! Very informative. There are a lot of variations in meters and I've notice some of mine don't like switch mode frequencies. You've got mean concerned now about the gate signal and damaging the mosfet with the input capacitance of the meter. Is there a fail safe way to check this? I've noticed you check it at the output of the ic, so is it safer to check the signal there because of the resistor before the gate, of can we put a resistor and/ or a capacitor in series with the meter lead to avoid damage to the mosfet? I don't often ask, but I think it would be worth doing a video on this. Thank you and have a great day!
@@HaseebElectronics sir I have check all capacitor and resistor all are ok optocuppler may be bad or not sir because with meter optocuppler value is good
I noticed that most of the uc384xxx the comp pin is connected to pin 2 through resistor and capacitor and the opto-coupler is connected to comp pin to ground. Kindly explain the reason for that and how to calculate the resistor and capacitor value for the compensation
I love your videos Sir . Keep it up 💪. Can you please share with me the details of your big screen multimeter so that I can get exactly the same type because I think It's great
Un saludo grande desde Argentina, muchas gracias por enseñar tanto ,a los los que nos cuesta entender los circuitos , un abrazo grande , que dios te bendiga siempre
The you my brother mohammad it very useful video and it very good method to test this series of this type Ices thank again for your efforts gad please you
Finally this kind of detailed videos I would like to see more of them in the future. Clear, detailed and very helpful. I would like to see you to use the oscilloscope as you mentioned also with clear instruction where to put what probe and how to set the scope. Thank you.
I'd only add one thing to your warning which comes on the very beginning on every video of yours is "Always use isolation transformer, during tests on switching power supply", but, that's just me. If they never do any experiment, they can't get ever any practical experience.
You are a persistent, generous and extremely ambitious person. Therefore, you deserve all the respect and appreciation from me and all the followers of your fine channel. Thank you.
