RTP cores - toroidal iron powder cores

Toroidal iron powder cores are used in DTP and DTSP chokes. The distributed air gap properties inherent in iron powder cores also make them extremely well-suited for a variety of energy storage inductor applications. The iron powder core is composed of an iron based, rapidly solidified metallic alloy. Unlike ferrite cores, the high permeability iron powder cores are capable of handling higher flux densities and higher power levels without saturating.

MicroR

MicroR is a Micrometals Inductor Software dedicated to design inductors mainly based on iron powder cores (except WIDE SWING inductors). MiroR assists in the designing of inductors depending on their six different applications:

1) Design of DC output inductors Differential mode inductors
2) Design of controlled swing inductors where the inductance does not exceed a maximum value at reduced current.
3) Design of wide swing inductors utilizing a composite core of ferrite and iron powder.
4) Design of a power factor boost or buck inductor, commonly referred to as a PFC choke.
5) Design of 60 Hz dimmer inductor
6) Design of a Resonant Converter Inductor

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 (i.e. Toroid, E-Core or Ferrite/Iron Powder Composite), 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) Micrometals 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) B ac
9) Percent Initial Permeability
10) Core Loss
11) Copper Loss
12) Temperature Rise.

In addition, new features alow the user to analyze specific designs as well as check the core's operating temperature vs. time for thermal aging analysis of designs. 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.
