Some one ask us develop new PA amp
My friend who manufacturing public address amplifier ask us to develop one new type amp,it will boost out signal voltage by high frequency ferrite EE transformer.
I think when we boost single frequency it will easy ,but audio signal and class D half bridge maybe hard to do.
Maybe class T have fixed duty cycle,should make it reality easily.
Please give us good ideas.

Oh!it's good idea but we have to use bigger transformer,if we use high frequency ferrite transformer before LC filter,the volume will very little.
No, the transformer size ("the volume") will be the same... Small transformer will go into saturation, whether it will be placed after or before LC filter

Oh!no,no,if we use a PQ3230 ferrite core it can deliver 400W power at 400Khz frequency under HB topic ,but when we use a toroidal transformer transit 400W power,10 times size.
Independent on the switching frequency, in your schematic the output transformer must be able to transfer energy of the audio frequency (starting from 20Hz). With size of the mentioned PQ3230 core it is only possible to transfer about max 4-6 Watts in audio band...
Sure, you will try to build this schematic anyway... please, keep us posting

Oh!we have to try it many times ,can you give us calculate methods for full range amp
Good idea!we think if the FeSi transformer can be used the ferrite core also works well,we can use air gap to suppress saturate.
I think the core question in this topology is how can we boost the output voltage and loader impedance matching .
I think we should talk about the output model ,and find calculating methods.
Any update?
I'd really like to know how to connect these modules as 4ch or 2.1ch before I order the Tas5613 variant.

4 channel and 2.1 channel connect method
Hi! Gal,
I upload wire connect and setting method here,pls check it,if you have another questions ,pls connect us.

Thank you very much !
These looks great and very useful for many applications.
Are the "2channel boards" that split the output into two speakers included in the "FULL FUNCTION" kit or needed to be ordered separately?
Can I order one kit based on the Tas5613?
Thank you again,
Gal

Ok!"2 channel boards" split the output into two channel,I think I can send
it to you as gift when you order some FULL FUNCTION AMP BOARD.
Thanks!
