xp-5000watts smps from detex audio,
how is this?
pls comment pros.

Let me put it this way: How close to the wall outlet do you allow your children to go with a screw driver - when they are in the shower?
Basic design, single layer, no real creepage or clearance gaps that are immediately apparent. it is a design done to a cost (as cheap as possible) it is not a design that has been optimised for high quality, I would be interested in the EMC testing results of this design. It looks like any other readily available budget PC power supply that flood the market.

smps circuits
schematic smps the good circuit,
please send to my email astra1_2008 at yahoo dot com
thank you brother,,.

Why is this design not good Im reading that a lot of people doesnt like selfoscilating smps? is it that bad? dangerous?
Can somebody explaine to me?
thanks

What is this topology? Not is half-bridge. 300 volts are applied to the primary, I'm uncertain about the ratio of turns between primary and secondary. In one cycle it applies 300V and other it resets the transformer?
I mounted the above schema and works.
The polarity of the gate driver is the opposite of Layout1. It is as described in scheme 2 handmade.
Ran 44KHz and I will have to increase the number of turns of the transformer because my saturated and heated. I used 19 turns on a toroid with 1.95 cm2 of Ae, which would give 2300g. I will increase to 30 turns and stay in 1500G.
It really is half-bridge, I was confused because one leg missing capacitor voltage divider (between transformer and negative), but the voltage ratio is like a voltage divider. I used 11 +11 turns on the secondary and got 85V +85 V

An externally hosted image should be here but it was not working when we last tested it.
