good day guys, I'm planning on building this amplifier, one thing that bothers me is how to make the inductor coils. you see, I don't have an inductance meter, can anyone help me on this, i'd also like to know if I'd be able to use my toroidal core ? thanks mates 🙂
EDIT: sorry, the pics are soo big, heheh my bad
cool pictures . about inductance try to use mini ring mini Ring Core Calculator it has most major cores but not all . i hope it will be of help to you . it is a very useful tool
if anyone has a link to a better program pls do post it's link.

Here is a simple web tool if all you need to know is the turns required for a specified inductance....
Toroid Winding Calculator ? 66pacific.com

The use of both N and P MOS FET allows here the simplification of the gate driver using capacitive coupling.
But the use of this topology for bridged amp is less obvious.
Still, it seems to be UCD.
erorr in my mind
i creat this but it have dc on exit
why?
these boards are diferent!!!!!!!
which one is correct?😕

I can't make an inductance meter, i don't really have knowledge about programming a PIC 🙂
BTW
an update to my project: i already have some of the parts but, I really do have troubles sourcing some of the parts locally hehehe 🙂

hi 1SaGing5
try talking to don2007ksa or irvynejay they are in your country they might know where to get the components.

i have not built this amp but the below link in post #139 i have tried and tested it 😎 😎

thanks to stewin
it is diferent with post #139
in this shematics and pcb the zener diods is diferent side
what?
which side is correct stewin?
can i use class d amp for HPF band like 6975 pioneer or tiuter?
thanks
what about the protection DC and OCP?
can you please send to me pcb files?
i am using protel dxp.
do you have it?
mr cpx try to hellp me but i can not do that beacuse i can not to find component and i dont have good knowlage.
thanks to cpx hellp.
thanks to you mr stewin.

the one on post #139 works perfectly i personally test it just use it exactly the way it is.
it does not include ocp protection .

hi stewin
i need OCP exactly for any amp i creat
how can i creat OCP for post #139 amp?

Hi.
I currently am building that amp too, and i've got two questions:
first, concerning the amp itself: is a T20-52 core suitable for this one as output filter?
I guess noot, but i am not sure ... or would a T34-26 be suitable?
second, will this amp interfere with a SMPS mounted in the same alu casing, running with 50kHz? there is about 25mm space between the amp and the SMPS.
thanks in advance 🙂

ok, i guess this will be trial and error ...
Thanks for the hint on the cores, do you know where i can get those? None of my suppliers (Conrad, Pollin, RS Components) has any Material 02 cores
