very nice work, will you be releasing an updated schematic ?
Thanks Reactance!
I can partially show the circuit diagram. I already showed the modulator, it does not differ from the previous model. I’m not showing the half-bridge driver yet, as this is at least some kind of know-how.
Now I am preparing documentation for the production of a trial batch of circuit boards in China, which will be available, including as a kit for radio amateurs in a few months.

I will be interested in purchasing I trust your work, update looks really good! please let me know about cost ect I will pm you with details.

Greetings!
 
So this is a rework of UcD high end modulator, isn't it?

Performance seems similar. This modulator shines at low volume and low frequency. Marketing arguments.

But hey, 0.15% THD at 5Khz high volume? I'm getting half of that with a 1st order modulator!!! haha

Hypex is not the best implementation of UcD. IMHO

0.15% on 5kHz :eek::eek::eek:

:yikes:Your skepticism needs to be updated.:D

You were mistaken by 40dB, and maybe more.
Distortions at 5 kHz do not differ from 1 kHz in the band up to 20 k and 1/2 max power.



UсD 1 order from the patent of the respected Bruno gives 0.008% if correctly implemented, 20-20k up to 1/2P. Just not everyone knows how to cook it
 
Video from post 15. Minutes 4~5. I was not expecting an emotional interpretation of a scientific statement. I will not make further appreciations.
Pardon, Eva.
In the video, a 500W power supply, and with a peak power above 400W, distortion naturally grows.
Near clipping, the loopgain decreases by 30dB, which just gives the desired 0.15%. (and due to the specifics of the limiter + some additional non-linearity) This is true for the output voltage below the supply voltage by 4V.


The other day I will definitely show a graph of distortions from power at 6 kHz for the version on silicon transistors.

Take a break Evita, let Sous Chill and enjoy his creation. :D
 
GaNFET drive

Experimental design of the amplification module for GaN FET TPH3206 from Transphorm.

Expected up to 500W / 8 ohm.

I think you are not easy to drive The TPH3206, the switch speed is too fast, easy to self-OSC, the PCB layout requirements are also high, you can try TI's drive all-in-one device, better to use , of course, Navitas is also a good choice, we try to use these devices on the 300-500 100V amplifier, At present, it seems that the effect is perfect.
