The schematic looks just slightly under average, but PCB layout is terrible.
There are better ways to do it with these parts (and TL07x op-amp triangle generator and LM319 comparator, standard stuff).
One of the things I have in mind is making a simple DIY-friendly class D module with through hole parts (except a few SMD caps) and a "DIY friendly" double sided PCB (no tracks on top layer, just continuous ground plane), and find out how good can I get it.

is this topology comparable to Hypex UcD ??

No , this is from Poland 'Praktikal Elektronik' magazine 1/2001.
This is classic topology with error amp, triangle oscilator and comparator, not self oscilating topology like UcD.
SMPS
Actually I wanted to make a SMPS for PA but I am afraid that the leakage current in the psu or something like a PC.
There are solutions to this problem?

U can use case of PC PSU for your SMPS, and find more information about leakage current... http://www.eetindia.co.in/ARTICLES/2004NOV/B/2004NOV16_POW_TA.pdf?SOURCES=DOWNLOAD
I did a similar project using a TL082 triangle wave generator, LM319 comparator, XOR gates phass splitter and IR2113 mosfet driver.
I didnt use any feedback at all yet it sounded great.
The only minor problem I found was I needed to null the DC offset using a pot or i got low level hum. Must have been an inaccuracy somewhere in the line.
