Hi Silvio,
VERY NICE WORK! CONGRATULATIONS!
How do you wind the two output inductors L2 & L3? I am wondering can these share a single toroid like a common mode choke.
I am planning my first half bridge smps. And I bought both IR2153 and KA3525, but cannot decide which is better in terms of stability and scalability. I opt for a 800w +/-58v 120khz as a start. As it is for hifi uses, low EMI and ripples are highly desired. I cannot decide whether it should have a output inductor.
Hi Silvio,
thank you very much for your reply. Your posts makes me think that this topology and schematic is absolutely doable. I will make my own half bridge smps soon. I may have questions and will come back to you.
ps. I cannot see your video cos youtube is blocked from my contry.
In the diagram, at the bottom right, be: pad 10, pad 11 and CT, what to be?
Also at the top of the center, on line 320v be connected aux + 15V. What is?
Be a small transformer .... I do not understand.
Be a nice schema, very safe and reliable, but do not understand something.
You can get +/- 70volt with +/- 15v aux and + 12v 1.5-2amper turbo fan
hi silvio,
i watched ur videos, very nice.
on full load what is the temperature of the etd49 secondary wire?
how many halogen bulbs u cennect for load?
is that bulbs very bright or les bright.
