Iron Powder Cores for Switch mode Power Supply Inductors
By: Jim Cox - Micrometals, Inc.
The purpose of this application note is to cover the properties of iron powder as amagnetic core material for inductors in switch-mode power supplies. The different considerations for DC output chokes, differential-mode line filter inductors, power factor correction inductors, and high frequency resonant inductors will be covered.
Iron Powder Cores for High Q Inductors
By: Jim Cox - Micrometals, Inc.
A brief overview will be given of the development of carbonyl iron powders. We will show how the magnetic properties of the iron affect inductor performance and will show, through example, how the physical size of a core along with its winding details interact to affect Q Vs frequency characteristics.
Iron Powder Core Selection For RF Power Applications
By: Jim Cox Micrometals, Inc.
The purpose of this article is to present new information that will allow the RF design engineer to select the proper iron powder core for inductors and transformers Handling power in the 250 kHz to 5 MHz frequency range.
