300W SMPS design .............. fully tested

[digits]

very interested man, re post 6, what is the x2 x3 parts, 3 wires or 3 layers of windings?

Also what is parts cost like compared to a 300VA transformer?

how you have selected a series capacitor of 0.47 micro F, to place in series with the primary winding of main power transformer ?

Nice desing! I want to try it to power 2 lm1875, but I have only EE35 ferrite cores from low cost pc power supplies and its very hard to buy ferrites. The market in my Country is very unfriendly for DIYers.
What do you think could I get with these EE35?
Can I use 2 or more cores in parallel to get more power without bigger mods?
Thanks

Without storage,hard switching smps wouldn't be good.Transistors works in capacitive region and after few hours-Booom.
