#276 SG3525A / SG1525A / SG2525A Pulse Width Modulation PWM / SMPS Controller

Nice video 👍👍

Hello friend, i want to vary the duty cycle manually ,between 35% and the maximum,49%, with a trimpot i have the china board SG3525+LM358, how can i do that? this for fase 1 of a solar inverter from 25 vdc to 380 vdc; thank you

Very helpful explanation. thank you

When I connect feedback to pin 1 and ground pin the IC just shutdown the dutycycle doesn't reduce my feedback voltage is 6.5v I connected the pin 2 to pin 16 please can you tell me why it shut's down when I connect the feedback

Thank you so much for making the time to make this wonderful video! I have a powered speaker with a power supply that uses both this KA3525A as well as a VIPer22A. The data sheets both say they are used for SMPS. The VIPer22A is used on the primary side of the transformer, while the KA3525A is used on the secondary side of the transformer. Can you comment on why someone would use both of these? Thanks again!

Sir g MashaAllah Bohat zabdust teachings sir ap ny lt494 ic data btaya plz is ka invater trasfamar farmola bts dain faratcor wala trasnfarmar ka farmola

excellent sir. thank you

Bagaimana membuat duty cycle automatic,jika frekuensi naik,duty juga naik

Improve your presentation by correct pronountions

Thank you bro. For this great information I have a question when pin 1 give 0 ohm with gnd this meaning get problem

I am looking at a schematic for a PLx- 1602 amplifier… it has a sg3525an, in power supply
The + input is tied to the vref(5.1v)
The - is tied to PRI_LO
So it’s full on all the time ?????

not subtitle😔😔😔😔😔😔😞😞😞😞😞😞😣😣😣😣😣😣😖😖😖😖😖😖😖

Hi there, i am having an 12v/220V inverter where the SG3525 AP is having 5,7v in the pin10 shutdown so the IC is not working. Where those 5,7v come from ? is it from the protection inverter circuit or it is a bad SG3525 that needs to be changed. Pins 13 and 15 are both linked to the same capacitor. Thanks

Oh, my friend, i vote you for college professor, i easily understood those explanations of yours.

Do you think that you can put out a video on the UC1526/3526ADW? It is virtually the same chip with 2 extra pins for Is+ & Is-. The datasheets I've found, leave much to be desired as far as as true mains AC-DC converter application. All I can find are instructions on how to make DC-AC inverter designs, which if working with a 12V starting voltage, can be realized via BJT's.

Can you tell me suitable resistors and capacitors for Rt, Ct, Dis to keep 30khz constant.🤔?

Nice explanation!

Nice explain

can you please make a video about making a inverter 50hz - 60hz with sg3525 with feed back ?
much appreciated !

How to by Pass the shut down pin of this ic

good work

Hi sir, one of the PWM outputs of this SG3525A is higher in VPP than the other output. This can also be noticed after the secondary rectification as one of the square wave is taller than the next one. What can cause this issue?

I watched your video on the tl494 and it was really helpful. This one is just as good. Thanks for sharing.

thank you for your lecture its more useful
I want ask you how can convert dc voltage 300v to sine wave by use SG3525 ??

I have the same microchip. If 1 leg rings on the 12th leg and the second leg rings on the 16th leg, the microcircuit is not working properly?

Thank u sir

AOA sir
Maany Sg3525 module banaya hy
Pulse teek araha hy
Lykin jab mosfet k sath connect karta hu to wave shape bigerh jata hy awr mosfet jaldi heatup hota hy
Kia masla hy
Please help me.

The power of the machine was doubled to melt 7 mm, but in it it was cut by welding the aluminum, then the yellow and red light flashed and remained like this and did not weld with changing 6 to 9 pieces What is the solution

Fantasticly explained sir, thank you very much

I have watch all the calculations videos and really understand, but you did not calculate the input pi filter(before transformer) and output lc filter, rectifier(after transformer) and full connection and calculation(practical) for the feedback using SG3525A , please can you help show us thanks.

Lovely video Haseeb.

Asalm aliykum sir so nice

waalaikumussalaam

An excellent detailed and nice explanation like always brother, keep up the hard work and keep sharing nice informative video. Thank you.

Sir hum China ups ka kam karte hai

ustad g ager ac dc fan ka card us ki 48 pin wali ic ko samjha den to badi meharbani ho gi ..

Nice explained ,,,👍

nice sir

Assalm alekum sir please Urdu mai

As always great video 👍

Pls.can u make a video about ic ucc3570n

Thanks for this great information

Very well explain sir

Nice vedio

A simple question...
This ic has 100Hz to 400KHz frequency.
How can get I 50Hz for inverter or UPS ?

Terimakasih selalu berbagi ilmu yang bermanfaat
semoga sehat bahagia dan panjang Umur Aminn

Wonderful upload dear friend, have a happy weekend!!!
