Hi Everyone,

I have recreated the MathCad design guide portion of the a TI APP Note for how to design an input filter for a switching DC -DC power supply.

The app note source material may be found here:TI APP Note

The SMath file may be found here:SMPS_Input_Filter_Design_TI_APP_Note.sm (555 KiB) downloaded 226 time(s).

The graphs are created using the ZEDgraph plugin.

Search Keywords:

Happy Learning!

Two comments:
1. Better generalize ... LOGLOG Zgraph application [typical suggestion].
So, the most naive search "LOGLOG" or Log log' will retrieve.
2. The way you index is not compatible earlier than your version.
That way of of indexing "Syntax error" is pure freak as applied.
Reserve it for baby stuff, local.

Worth visiting Matrix(n,r,c,α,β)
All my advanced algo are on that style.

Cool stuff. As an EE having once specialized in PS design this is really cool.

Just as a side note.. I was able decrease the calculation time by about 1/2 by setting optimization of the whole sheet to numeric. SMPS_Input_Filter_Design_TI_APP_Note_alyles.sm (557 KiB) downloaded 109 time(s).
