I'm looking for a full-bridge converter project. I need a schematic
preferably to build from. A parts list would be nice to. Or maybe a
reference to a site with DIY SMPS. I'm looking to design a 1.3kW power
supply and I need to experiment first. Any articles, references, or books
with ready to build schematics would be wonderful! They don't need to be
1.3kW supplies but it would be nice to just get some experience building any
full-bridge converter.

Have you looked at the application notes for some of the full bridge
converter control ICs?

I have just completed a full bridge converter design and am about to
make all files public. Artworks, simulation files, design notes, etc.
Can you tell me a little bit more about your application? I might be
able to help you out.

regards,
Bob

I don't really have an application I just want to make a nice power supply
for my bench.

What size would a full-bridge converter for 13kW be?
Would you happen to know of a website with information on that? Or is there
a fundamental measurement for a per-watt approximation? I have just been
doing calculations from formulas I get out of these books I bought. I'm
going through and studying and this full-bridge rectifier looks like it
could be an interesting POWERFUL project! What are typical ratios for the
transformers? Where do I get these high power transformers? Can I get ones
that operate much higher than 50-60hz?

Bigger than a breadbox. ;-) I think he was being sarcastic. 1.3Kw is a
_lot_ of juice to be messing with for your first project.

Good Luck!

While I would hate to dent your enthusiasm for such a project Hudson,
the questions you raise here are indicators that you have absolutely
no experience in the design of high power electronics, let alone any
other area relating to electronics. If it weren't for your apparent
sincerity in these posts I would almost think you were trolling.

While not wishing to sound nosey or impertinent could you please give
a brief resume of your electronics background/experience and
educationional level, just to aid us in assessing your current level
of knowledge and whether such a project may be within your realm. I
can tell you that what you are proposing would be extremely daunting
even for a highly experienced electronics professional with many years
of design experience specifically related to smps design. With
respect, you come across as a complete novice in this area and what
you are trying to do is run before you can walk. You need to first
design simple PSU's and work your way up.

If this offends then I humbly apologise for any hurt.

I have my A.S. degree in electronics. I have experience with
microcontrollers, and I don't need to build a linear regulator because I
have repaired them before. I'm just in experienced in the area of SMPS which
is why I am so enthusiastic about it. They seem to be really neat. I'm
paticularly interested in reading some notes on making a buck regulator to
REPLACE a step-down transformer/filter/linear regulator supply, like what
regulator/controller to use for what application. I was thinking about
making a simple buck regulator to plug into an AC outlet and use it to power
a PIC, I even designed the coil and filters in spice simulation software for
those power requirements. I just need to find a controller or regulator to
use. I have bought EDN power supply design, and switching power supply
design. They gave me a good understanding of how they work, but I'm just
empty on projects. Yes I am unexperienced at designing SMPS. But anyone with
a fundamental AC and DC theory education can understand this paticular
application, and I do because I have taken the time to start reading about
SMPS.
