UC3842 Switching Power Supply For Battery Charger 3-15V 10A 

No ! He said the IC works on 10 V but better to work on 15V !

Yeah. The feedback should take care of regulation. Just ensure you use a good snubber network (use at least 2W rated resistor and a good quality capacitor because they can get quite warm)

Sure

@@ELECTROBUFF What is your ferrit transformers type of this project ? How if I want using EE25 for this project? does worth it?

@@farosrohmangeloraramadan3897 EE25 is not sufficient for such power try EE35 or EE40.

just adjust the variable resistor to get the appropriate and desired voltage

I wanted to increase the range

mohit if you get to know do share with me

can be

Your right; I've tested a few uc3842, uc3843 and 3845. The uc3842 turns on with a threshold voltage of 16 volts; the uc3843 with 8.5 volts. After turned on you can set the uc3842 to 15 volts.

Sure. Current sense resistor provides feedback to pin3 on the primary side. In case of a short circuit on the output, more current will be drawn on the primary side (primary winding) causing a ramp up of current. I've set the maximum current flow on the primary winding to 5A, otherwise feedback causes the IC to cut off its PWM output. Also there's a Fuse in case everything else fails. In the video I mentioned you can optionally use an op amp for both voltage and current sensing on the secondary side and together with the optocoupler, you can provide feedback to the IC. So, both current and voltage control is very possible with a simple adjustment.

Thanks very much

I would also like to suggest that you do a video on how to make an ac 500w inverter that has regulation and feedback pls Once again thank you

How to raise the isense ampere? Every time i charge old battery The charger keep turn off

@@testaja3614 obviously use a lower resistance current sensing resistor and include an op amp for better gain and control

It's possible, but that will reduce the maximum power due to the hysteresis effect involving the ferrite core meeting the ferrite core

Bu oradan buradan arakladığı devreleri kendi yapıyormuş gibi anlatan biridir.Bilgisi olan biri değildir.Sorunada cevap vermez muhtemelen

@@Yorumcu63 RU-vid da kim kendisi gerçekten devre tasarlıyorki? Millet sadece para üretme peşinde, fikir, ürün, teknoloji, sıralamada bile yok.

What is the solution to get to 10a

May be it is 10 amps at 3 volts

The duty cycle of uc3842 ic is less than 50% and will change depending on how much current is going through primary winding of transformer and feedback from optocoupler pc 817 and tl431 voltage reference.

usually for the first layer there is a primary winding with a total of 30 turns, and the second is a secondary winding with the desired number, and the third is a feedback or auxiliary winding with the number as needed, then the fourth layer is a continuation of the primary winding from the previous primary which is wound in the same direction.

The fourth layer is the primary winding, totaling 15 windings, sorry I forgot 😂

We just learn, grow and better ourselves over time.

nothing important I have work with both of them and run the circuit with UC3843 AND UC3842
