Release Notes

This is the current release of the design software from Micrometals Arnold Powder Cores (MMAPC). Only the modules for DC Biased Inductors and PFC Boost Inductors are functioning in this release. Also, only designs on Toroid geometries are available at this time.

MMAPC believes the information to be accurate. It is important to note that the default settings can be altered and unacceptable designs generated. Before using this product, the user agrees to determine suitability of the product for their intended use or application. MMAPC shall not be liable for any loss or damage, including but not limited to incidental or consequential damages as a result of the use of this software.

Any feedback on the software would be greatly appreciated. Please send comments to applications@MM-ArnoldPowderCores.com

MMAPC will gladly offer engineering assistance and provide samples to aid in your core selection, please do not hesitate to contact your local representative or the factory directly.

MMAPC Inductor Software is a flexible user friendly tool designed to assist in the selection of iron powder cores. The software file size is 4.5 MB.

The user will have the opportunity to select from two different inductor applications:
1) Design of DC output inductors Differential mode inductors
2) Design of a power factor boost inductor, commonly referred to as a PFC choke.

The program accepts user defined design requirements in terms of required inductance, dc resistance, dc bias current and applied ac voltage. The user has the option of specifying core geometry (Toroids only in this release, specific core materials or all materials, metric units or English units, maximum window fill factor, temperature rise, ambient temperature, etc.

This program will automatically calculate the smallest core size possible and will display;
1) MMAPC Part Number
2) Approximate unit price
3) Core AL Value
4) Required Number of Turns
5) Wire Size
6) Percent Window Fill
7) DC Winding Resistance
8) Bpk - Peak AC Flux Density
9) Percent Initial Permeability
10) Core Loss
11) Copper Loss
12) Temperature Rise

In addition, the software allows the user to analyze specific designs using the analysis function.

The software allows the design engineer to quickly work up multiple design solutions based on user specified electrical requirements which all can easily printed for hard copies. Designs can also be saved to a file by using the 'F' key.

The design program is automatically set to default to an ambient temperature of 55°C in free standing air with maximum temperature rise of 40°C.
