(or are there different ERL-35 layouts??)

Itsu,

Yes, the ERL-35 is the core type and there will be various winding configurations used for PC PSU's. The particular winding configuration shown in the spec you posted, clearly does not allow the transformer to be used in a step-up config. I found a transformer from an old PC PSU (with codings TF-463 & LS-130B-1) that measures out as suitable for step-up with a ratio of 1:5.

I am wondering if this is the missing part of the Kapanadze puzzle.


Any constructive comments??

I believe the FE diagram is here http://www.gestaltreality.com/energy-synthesis/eric-dollard/additional-posts-by-e-p-dollard-2012/

Hoppy,

Ok, good to know,

i will check my transformers for a useable step-up with a ratio of 1:5

Itsu,

Thinking about this further, as this is reasonably low powered forward converter, you should be able to drive the primary unipolar, so not needing a centre tap winding. So any main PC SM step-down transformer working reversed should work to give the required 300V DC output @ around 0.2A, when rectified and smoothed. I'll have to try this out myself.

Itsu,

I setup my transformer with a PWM drive running at 31KHz with a 24V supply. The output was rectified and smoothed with a 33uF cap. The most efficient running with best 50% duty waveform produced a DC voltage of 98V across a 1K load resistor (200V pk-pk across transformer output). The supply current was 0.22A. It would appear that the turns ratio of 1:5 needs to be increased, so its quite possible that the transformer in the ALLEGGA circuit was custom wound.
