Runo's Power Design
One of my most important tools is
Mathcad - a mathematics software, in which I have
developed a variety of tailor made and specialized
worksheets intended for typical SMPS design.
Here is a small selection - some of them with examples of
results shown in PDF format:
"discontinuous" as well as
"continuous current mode" and "boundary conduction mode".
Booster for "power factor correction"
with fixed frequency.
Booster for "power
factor correction" with variable frequency -
"boundary conduction mode"
Boundary Conduction Mode.
Booster as a DC - DC
converter (buck with transformer).
Full bridge, half bridge and
bridge and full bridge resonance converters of the LLC
or the LCC
type. Also see my guide to the LLC analysis worksheet here.
Inductor design, airgap,
Feedback loop with open loop and closed loop phase- and gain
curves and step load response. A simple
and a little more advanced example.
See also this article. Or this:
Buck Converter Loop.
Spectrum of conducted emission and calculation of the
necessary noise filter.
Still today, new worksheets are
occasionally added to my assortment. By virtue of these
tools I am often able to hit very close to the target in
the first shot.
I find the "Try something - see if it gets
better"-method very insufficient if it is used alone.
