Hello friends ! I have many different E , EI , ER, R cores from different manufacturers I bought sometime.
I need to determine mu permeability by using a simple method, using a sine wave generator, and oscilloscope.
Earlier today I took one E 30/15/7 no gap , and calculated an inductor...
My friend once more I thank your good will.
It is always a good opportunity for learning.
In my case I am a logic / digital / microprocessor / industrial control designer 35 years now. I forgot about ferrites along time ago, but I don't loose the hope of learning.
So it is easy to use one of...
For the reasons exposed about the chip ( please I suggest to read the information ) I will choose flyback.
Only if you share the same information that I am talking about we could work on this issue.
I appreciate your opinion but for many reasons I need to use this line of products.
Also, maybe...
My dear friend, I thank your intention in replying.
I have some experience in low frequency switching power supplies up to 50 KHz.
I have designed some of them using the old and fantastic TL494, and built my own tranformers.
This device works at 132 KHz and need much more experience.
Why flyback...
Good day and thank you Goldsmith.
Well you have the complete circuit schematic.
This is a 24 V @ 10 A output power supply.
Here are the parameters from the design program PI Expert
One of the problems is that this program is not able to design for the StackFET configuration
TRANSFORMER PRIMARY...
Hello ! I consulted Power Integrations about a power supply design using one of their TOPSwitch IC's. The details of my questions are here:
**broken link removed**
I have almost everything figured out, except for the snubber network for the StackFET configuration. This is used to improve the...
