Have you talked with the Payton Group in Israel?

:http://www.paytongroup.com/worldwide...or=changcolor1

They are a specialist regarding transformers for SMPS´s

Maybe you could buy what you need from them (or getting a sample)

Found also this web-site:

I am wondering what happened to all those big toroid cores. You broke one as a sample to display to the group. I am mainly just curious.

oh , u still remember those?

i still got em , they arent working too good , the radius of that core is too big while the material area is too small .

try www.edcorusa.com. we ship quite a lot to Israel

Hmm. Do they mainly take up too much room, or does there seem to be some adverse effect from that type of form? I have some Phillips surplus toroids that are about 1.75" outside diameter (OD) and 1.25" ID. They seem to work fine. I find them easier to wind, even.

Hi,

If using the large power like 600watts, it would be better to use switching PSU, today, switching method is widely use in most application. the design is more and more stable, such as ripple, line and load regulation, over shoot, under shoot, recover time, and hold up time -------- etc. improvement has been made to switcher. u can consider switching method.
