I got mine a few weeks ago, but I have not had time to "play" with it yet.

The board quality is very good and so is the assembly - I did not buy the kit since Cristi was running out of boards due to the success of this project. Well done!

I understand that a new version is in the works - I will keep on watching...

Regards,

For an "open" project its a bit too secretive.

Its kind of difficult to register on that forum - I've tried twice with no luck, you are not answering to the emails sent from your website, I see not even a schematic here..... 🙂

I wanted to buy a pcb for the smps, no hidden agenda.

Can I when rewind use 2 x 120 volts 400 mA 12 volts 5 amps 300 volts 150mA and 2 x 65 volts 20 amps?

I think then I need a bigger core and remake te pcb, this is for a hybrid, I was already busy with a soft switcher but saw this thread. A resonance soft switcher is very quick in regulation respons and it is soft switcher, so nice sinusoidal output less harmonics so better cleaner output filtering.

Included transormer calculator in zip and a diy supply on link who can be used as a basis for a good supply.

High power adjustable switching power supply (SMPS) 3-60V 40A
