Simplicity Facilitates Magnetic Component Design

Latest Generation Of 3D Electromagnetic Finite Element Analysis Software With Breakthrough Simplicity Facilitates Magnetic Component Design

by Peter Markowski, Envelope Power, Ansonia, Conn.

Finite element analysis (FEA) software is a great tool for simulating electromagnetic fields in chokes and transformers, allowing accurate computation of the spatial distribution of the current, flux density, associated losses and resulting temperature rise as well as the impact of the magnetic component on the efficiency of the converter. By manipulating dimensions and geometrical arrangements we can arrive at the most compact, efficient and lowest-cost structure. Unfortunately, 3D FEA software gained the …
