Thankyou KlauST for your reply. I will make corrections in the layout and schematic. Is the arrangement of the components fine? I will increase the spacing in the high voltage side. ThanksHi,
There is not sufficient clearance and creepage distance to fulfill safety standards. Don't hurt/ kill yourself or others.
I even suspect there is not sufficient functional isolation clearance at the high voltage side.
Then there are no GND planes. Expect increased ringing and thus increased EMI radiation.
This does not meant that it does not work.
But even if there is the correct output voltage .. this does not mean it is safe ... or legal.
There were similar discussions before...with detailed discussions. Just fo a forum search.
I doubt the output voltage feedback can work. I see just one trace from the output capacitors to the optocoupler circuit.
This way I'd say there is a good chance for overvoltage at the output ... the output capacitor may get overcharged, explode and catch fire.
My recommendation: Don't try to build this circuit now. Please start with less dangerous designs, first learn about safety standards and PCB design.
HI Andre_teprom,You likely did not took into account Klaus remarks regarding to safe clarance. I also would be concerned in some dimensions, such as the diameter of the U1 pads which could spread out over the solder each other, as well as the hole diameter of transformer pads that seems undersized.
