Does anybody have experience with this technology?
Pascal - High Power Pro Audio OEM Amplifier Modules
Is there eny explanation how the control structure works? Is it patented?

One of our members seems to be working in an enhancement task force for this circuit.

so the PSU for the X-Pro 3 is a single stage flyback PFC with mid-sized coil. And they claim >2KW of output power ? lool.. i guess it ll be more like a few hundreds of watts
I would not expect that it has PFC.
The huge caps on the primary indicate the opposite.
There seem to be two switches on the primary.
I would not expect a flyback there (neither with paralleled switches nor an asymetrical half bridge flyback), it is looking more like a typical half bridge converter. Series resonant or LLC.
The smaller transformer might be a flyback for auxiliary supplies, but that's also making me wonder, because auxiliaries could be derived from the main transformer as well.
Just buy one, examine and tell us 😀

Fact is, I am searching for a full bridge class D assembly to run on 175V, so I came across this part. I have good telecom rectifiers, so no need for built-in PSU.
Background of the story is: I d like to put 4 full-bridges together with my rectifiers in one case of ~4U height for a 4 ch amp (2 x RCF Event 4000 tops and 2 x 18G50 woofers). This would give a nice system for my garden home discotheque. At the moment I am more inclined to buy 4 x UCD 2K, but still thinking..... Does anyone know from where within the EU to get the UCD assemblies at a reasonable price?
Make sure that you always invite your neighbours 😛😛... for my garden home discotheque.
...hypex has its price... I am not aware of discount sales channels.At the moment I am more inclined to buy 4 x UCD 2K, but still thinking..... Does anyone know from where within the EU to get the UCD assemblies at a reasonable price?
Looking at the cost of 4 x UCD 2K, it ll maybe significantly cheaper to use 1 x UCD2K for the 2 18" in parallel and 2 x UCD700 half bridges for the Tops....hmm... still plenty enough power and headroom for this system, but less versatility for other systems...
