I think i will build one 300w a simple one based on ir2153
Would that mean you look around for a power supply design based on the IR2153, and just clone it, or do you design up the circuit and select all the off-the-shelf parts, and design up any transformer and pcb parts, and then measure/adjust/remake to meet some target?
...or do you design up the circuit...
What is there to design about a SMPS so simple as it is with IR2153?
An excellent question to ask klevismuka a few times as he progresses through to a finished project, as he seems to have a clean sheet starting point and no target outcome apart from 300W.
Aren't we a bit too picky?
IR2153 provides one of the most basic half bridge power supply, there aren't much choices to be made, so there isn't much to learn from it but the most basic principles of the half bridge converter at work.
I would recommend it only if there is a real need of a very cheap and simple couple of hundreds watts of power, otherwise... But now i am picky 🙂

Let's see what design issues are raised along the way - we've already had posts commenting on creepage and clearance, and core size and frequency, and pcb layout, and haven't yet seen anything on junction temps or step response or over-current protection, let alone looking at a 7815 datasheet to appreciate where that may go wrong.
I'd suggest for a smps noob with a keenness to learn and appreciate, then the 'simplicity' of a low power half bridge is an excellent training project. Nothing like an active forum to oversee a project and add lots of well-intentioned critique, if the OP is up to the scrutiny. There are lengthy threads on here just about grounding in a linear supply - what more interaction could one want 😀

Or to put an end to it 🙂
This topic proves that.
If you stop everytime people say you should, you can never grow.

Heaven forbid others experience may actually save the life of someone with less (or no) real world experience.
Then again, one less engineer can't be that bad can it.
They say you learn from your mistakes.
But some mistakes will only teach those who attend the funeral.
That's an excuse used all so often to put an end to someone's project.
A basic 100W power supply ( say with IR2153 ) can kill you, debugging an ATX power supply can kill you, a simple 10W flyback converter can kill you, anything powered from mains voltage, can kill you just as easily, but that doesn't mean you should stop building stuff for fear of death. Fear it's self can keep you safe, it makes you pay attention, be carefull.
You seldom save someone's life by convincing him to build something simpler but still powered from mains, but if you try to teach him some safety rules, share your experiance, then yes, you could have saved his life.
All the best.

Sorry, clarification.
I'm not saying he shouldn't do xyz.
Just that he should look at what others have said and tread with caution.

Hi, thank you all for replies
I think i will build one 300w a simple one based on ir2153
you can make 300w with tea1610p its very simple and running cool.
so this 3kW project is stoped?
