Hello
I really need your help
I need a circuit to change amp of Pwm
Input : pwm 12V 5Amp
Output: pwm 12V amp between 15-50 amp
I have to say I don't know programming or program any type of IC
I know I have to pay money for design a circuit like thus, but I live in Iran we can't and don't let transfer money to outsideof Iran
Please help me
Just draw it on a paper
Thanks

 

Welcome to AAC.

What will the output be fed to?
What frequency is the input signal?

 

Welcome to AAC.

What will the output be fed to?
What frequency is the input signal?

What will the output be fed to: for a lot of linier led

What frequency is the input signal?
I don't know I am using a sensor that I can control bright of my leds, but this I can't control a lot of led by this .this sensor
Thanks for answering me

 

I think what you really want is a variable power supply that uses a PWM signal to adjust its output. But without technical information on the switch it is really impossible to help. I'm sorry.

Can you look at this circuit
I don't know it's good or not even I don't know about input of this
Is this useful?
The designer of this circuit doesn't answer me , and also this page is in Persian
Can I use of this ? Or is it to possible to change this circuit for my goal

 

It looks like it could be a possible solution. It is a MOSFET driver for LEDs but I don't know what the signal you want to use looks like so I would just be guessing. That circuit is, apparently, to allow a low output RGB driver to handle more power but it's not going to handle 50A, that would require much more cooling than is on that board.

You just don't have enough information about the output of the switch for anyone to really help you.

Can I increase this to 10 channels and their inputs are the same and I also connect the outputs? For handelling 50 amp and also heating.
Is it possible?

I know that maybe my solutions are so stupid but really I have to do it
I live in a small Village and I don't know why no one does not answer me in my country

I am sorry I can't really help you because you don't have enough information. Anything I would tell you would be nothing but a guess.

Thank you so much my friend that you answer me and also you share your information to others
I am a teacher and I appreciate you that you wanted to help me

 

If I had a way to help more, I would. It's frustrating that you are so isolated. The easy way would be to buy something complete. But even still if you could measure the output, etc. It would possibly make some difference. I hope you find a solution.

Can you tell me how can I measure it or it's difficult and I can't

You would need an oscilloscope to do it. Even then, the process of successfully building a circuit that does what you want through messages when you don't have any independent knowledge would be maddening and almost certainly fail.

I can feel your frustration but it would only increase with this approach. Somebody local is the right answer even if that is also hard or seems impossible because in spite of the fact that you can talk to me, it is practically impossible to help you.

OK, I got it , thank you so much my friend, I hope you always be fine with big smile
