Ferrite Design Program An extremely
useful tool from Epcos which allows accurate air-gap calculations on E
cores, THD distortion, core Power Loss, high frequency AC winding loss
and inductance vs bias among many other. Also contains complete
catalogue data on entire Epcos ferrite range.
|LTSpice Excellent Spice version from Linear
Technology designed specifically for SMPS circuits. Includes non-linear
magnetics models. Has a very active users forum.
|Femm Powerful 2D Finite Element Analysis from
David Meeker. Not the easiest to use but can provide very accurate
results. Website contains a number of tutorials to get you started and
there is a users forum. Well worth the learning curve.
|Magnetics Inc Suite of designs programs from a leading
core manufacturer. The Current Transformer and Common Mode Choke
programs are very limited but the Inductor Design program is a very
useful tool which allows comparison between MPP, Sendust and High Flux
|Micrometals Iron Powder choke design program. Has a
great Analysis mode which allows 'what if' scenarios by changing
core size, turns etc.
of programs specifically for amorphous and nanocrystalline cores.
|PI Expert Power Integrations program calculates
transformer designs to work with their range of switching ICs. Gives
very detailed build data.
version of Advanced Power System Simulation Software. Very powerful yet
easy to use SPICE-based simulator.
