looks like the same guy is asking for the same on other forum i did a google on it and same nickname appeared
if u havnt much experience in building things like with high wattage expect some puff of smoke and maybe even vorse

start with something simpler or not that high in power might work to start with and less expensive components to fry

Hi,
The Buck Boost Circuit you have attached is of Primary level. With this level of understanding, it will be very difficult and unsafe for you to try to construct Buck Boost Circuit of the specification you have mentioned as Buck Boost circuit is one of the complex circuit in smps. However, what is your input voltage?
What is your background? Have you handled smps circuits earlier? Do you know the configuration of SG3525/TL494? Please let me know, so that I can help you by assessing your understanding level.
Trying to construct circuit by only following schematic in smps is dangerous and useless.
