I make such power supply boards
push-pull without stabilization.
not galvanically connected to the primary side
power up to 500W
additional output +/- 12V
and 12V relative to V-
Current protection, overheat protection, stand-by signal generation for the amplifier. Protection against low battery power.
Latch on an external error signal (constant voltage sensor at the amp output).
About 89x99mm

The Ucd102 needs 36V.
Sous,
It appears those have the transistors located such that attaching them to a heat sink would be difficult. Do the transistors on the bottom of the board need to be sinked?

100W works without a heat-sink.
But for the automotive use, you still need a case.
It’s convenient to use any flat-bottom case

The Ucd102 is 100Wx2 for 200W total. I would not run it like that though. Normally I wouldn't be running over 10W total.
So it will supply 36V? Can you ship to USA? Price?

Did you make the PSu How can I get it. Want to use my Hypex module in my car and Bike.
Hi Sous, can your PSu deliver 20A? I'm having a difficult time sourcing a DC/DC converter with 12vDC input capable of delivering a +/-36v output with enough current capability.
Power rating for 20A at +-36V is close to 1.5kW 🙂 12V car electric installation will need to provide 110-125A of current at full power 🙂 that's a lot
I'm also interested in properly designed DC-DC converter, that can achive ~700W of power. If output regulation or some kind stabilization would be an option = that would be perfect.
few weeks ago i've bought DC-DC converter from aliexpress. it was advertised as 1kW capable but it's input fuses are 2x 20A.... those can be swaped, but probably there is a reason why those are not 50A 🙂
so no more than 500W at input and 450W at output if i'll be lucky. but those converters have an issue - it's output voltage is tied to input: it provides +-36 @12V input; with 14V input output voltage is close to +-40-44V. voltage spikes can be as high as 15V at input.
either way, i will test it in near future (2-3 weeks) and check what's possible with these converters,
i have DC load and thermal camera but waiting for osciloscope.
