norazmi,
if your up to DIYing the coil, you could also use an medium size E-E ferrite core(gap it at the center) say 1mm and wind your coil at the bobbin.. it helps to have an LC meter to measure inductance...

Ferrite is good, but for high power (~1 kW) 1 mm airgap is not enough, 2 mm needed at least (with 2 cm^2 cross section).
EM radiation "leak" on the side leg/s ....
a compromise must be made for FEW turns && inductance && saturation... better if an LCmeter is at hand..

I don't know about in your country, but here in the UK it is much easier to buy ungapped cores in small quantities. For prototyping I use these, and then cut-up pieces of old credit cards, or business cards to use as the gap spacers.
Yes i do that, im trying with EE and UU small and medium size, but from my ear why is iron material gives good on bass sound better than ferrite, or maybe i dont make correct winding on ferrite core, idk.. i just tried with gapped ferrite toroid too but its same as when use EE and UU core hmmm, any ideas? So far im using T106-26 toroid iron with 18 awg sounds good so far heat not too much can be touch even i`m playing loud at full volume with +- 50 vdc. No noise at all when using linear power supply, but be carefull when using offline smps u need to have good filter for it.
regards.
Azmi.
well, its 'simpler' to DIY an LCmeter (google)... thats what I have... I don't have a descent scope ATM
Bonjopur, I return to the topic I made progress. I simulated the LTC software schematics Attached Files IR2110_UCD.zip (421.1 KB
But that does not give me a correct answer!
my questions
someone does make this amplifier
which simulate the schematics on LTC.
Thank you for your cooperation.

hi quinquin07 i built the amp and it performs great http://www.diyaudio.com/forums/class-d/166214-ucd-25-watts-1200-watts-using-2-mosfets-11.html

Bonjour, je vous remercie pour votre réponse, mais je copie les schémas de simuler sur "LTspiceIV de la technologie linéaire, mais je ne peut pas tourner, est-il une erreur?
Je joins les fichiers.

Hello, thank you for your reply, but I copy the patterns to simulate on "LTspiceIV of linear technology, but I can not rotate, is there a mistake?
I attach the files.
Greetings.
