Incoming Inspection Testing on Soft Ferrite Cores

blogpost header image

Many a times power electronics engineers find magnetics design as a complex process and when it comes to incoming inspection of ferrites – many have very basic knowledge and lot of misconceptions. Here’s a good application note on the same. Research paper originally appearing on MH&W International Corp. NJ, USA.

The Difference Between Inductors and Transformers

Transformers and inductors seem very similar in a visual and construction sense. However, they have different applications and have their unique design and construction elements. Below is a summary about them both, which provides a little guidance on the differences. Inductors An inductor (also called a choke or reactor) is a passive two-terminal electrical component. It is made of …

Types of Magnetic Core Materials for Transformers

The electrical power transformer features primary, secondary, and tertiary windings. The flux between the windings drives the transformer. Magnetic cores are used in transformers, which serve as the pathway of the flux. The core can be made from various materials. This post discusses some of them. The magnetic core is a material with magnetic permeability, …

Ferrite Cores for Engineers: The Definite Guide

An electric power transformer features primary, secondary, and sometimes tertiary windings. The flux linkage between these windings drives the transformer. For effective flux linkage, one low reluctance magnetic path is provided in the transformer. This path is known it typically in the core. Generally, the core is made from different materials like silicon steel, ferrites, …
