{777} UC384x PWM Controller IC Test Circuit, Test 384x Series IC

Thanks❤

1-st Class Job !!!

Nice video and Thanks for sharing the information. One request to upload video of UC3825DW PWM controller

nice setup!!

wonderful,what is the rating of mosfet with GAE741 number?there are no datasheet..thank you..

irf741 and GAE741 is the same rate mosfet?

👍👍👍👍👍

Lk 101 brother 👍👍👍

A first class tutorial, thank you and stay well.

wow great

👌👌👌👍

Very nice information sharing. Thank you sir.

That’s an amazing video and Allah bless you❤ please I have a technisat Audiomaster mr2 and I want you to show me where to get the service manual. Thank you🙏🏽

informative sharing 👍

This will work out if you have scope equipment. Good for those. Me I can tell duty cycle on 555 timer if I put a bigger cap on it to slow oscillation. Might got more out of it if you can tell without scope.

Teşekkürler kardeşim.Bize verdiğin faydalı bilgiler ve samimiyetin den dolayı saygı ve selamlar sunarım.

Aslmuailkum Bhai

i am not very clever execuse me.5 🙏.

Subha Bakher Ho Janab Bhai Sahib

Amazing, great lesson sir!
it seems like to steampunk art 😉!
Thanks a lot

Assalamualaikum, the video is very good, thank you very much, inshallah, I am waiting for your next new video,
stay well,always take care of your family, Allah Hafeez.Assalamualaikum👍👍🙏🙏🔔🙏🙏🔔🔔////////////////**********...............*/.*/..//*

Sir is ko urdo Kia kia jay to hamary ley asany hogy

I want to correct the author a little, the microcircuits of this series differ from each other, for example, UC3842/44 is different from UC3843/45, instead, 42 is interchangeable with 44, similarly to 43 and 45. the best option for the construction of power supply units is microcircuits of the 2842/43/44 series /45- the temperature range is different. we carefully read the datasheet and look at some power parameters and voltages at the outputs of microcircuits.

ماشاء اللّٰہ سبحان اللّٰہ

Great Videos. Your explanation is Amazing. Thank you for putting time in this.

Excellent thanks for sharing

hello sir, wonderful explanation. can this IC be use as voltage mode PWM controller?

you are great sir

جزاک اللہ خیراً کثیرا

Спасибо. Хорошее видио!

Excelente.

Teşekkürler hocam ağzınıza sağlık 🤲

Great video

Asalam Aliekum walhamatulahi wabalakatu thanks it's so nice

Sir, I have one uc3845 on welding machine and I find these values : vcc 12.2v, vref 5v, output 1.3v DC and 0.2v AC, frequency on output 96kHz and duty cycle 11%. How can I find 96kHz frequency ? I think I have to measure output in AC not DC is that right ? Output goes on MOSFET gate and I have 378v DC between drain and source. Do you think my IC is dead ? Thank you for any help

هذا ما كنت ابحث عنه ممتاز ممتاز ❤

Hello Hasseb Sir
My pin number 4 droping to 0 volt wheni connected in circuit ,Can you expalin what can be the reason?
Thanks
Dal

Sir can we replaced UC3842 instead of UC2842 plz reply plz plz plz

Дякую друже за схему та пояснення! 👍

Please this video from Urdu

Great, but what if I want to stop the current mode controlling.
What should i do ?

sir how is the duty cycle set to Ton time in pwm controller uc 3843

wonderful explanation. I urge you to classify your explanations to different PWM ics to series .thank you a lot sir

Mam w naprawie dziwny zasilacz impulsowy na tym układzie scalonym uc3845b (16,5V 12A) bardzo mi pomógł Twój film.

Masha Allah

app paid project bana saktayn han kya?

Hello! I assembled the circuit and it worked perfectly. I made a small modification to the output of IC pin 06. I replaced the 1K resistor R5 with a 2.2K one in series with an LED. With this modification, in the absence of an oscilloscope I can vary the brightness of the LED and observe the PWM modulation and make sure the IC is good.

sir your videos are amazing kindly ye btaein k agr ksi chopper ki frequency maloom krni ho k wo kitni fequency p chlega tau kese maloom krein

HELLO SIR IS THE KA3843 SAME WITH CU3843? I REPLACE THE KA3843 BECAUSE ITS NOT SENSING THE BATTERY POWER (ALWAYS SHOWS BATTERY FULL EVEN WHEN I UNPLUGE THE POLES OF THE UPS FROM THE BATTERY AND HAVE 27.5 VOLTS OUTPUT ) WITH TH CU 3843 I HAVE BATTERY SENSING BUT 0V OUTPUT NOT CHARGINGTHANKS IN ADVACED

A gerat vedio as usual...Thank you sir for sharing ...i made it using uc3843 but the max duty cycle is 97.6 ...Why?
