Default Hi sss

Have you talked with the Payton Group in Israel?

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

They are a specialist regarding transformers for SMPSīs

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

Found also this web-site:
http://www.iaei.org.il/Company1.asp?sub_m=2&id=228

Regards

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.

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.

Default 600watts core

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.
