New generation of 3D electromagnetic finite element analysis software with breakthrough simplicity facilitates magnetic component design
By Peter Markowski, Envelope Power, Ansonia, Conn.
Multiple layers of conductors in transformers can increase copper losses many times due to the proximity effects if the conductor thickness is higher than 0.3 of the skin depth. Traditionally used Dowell’s curves are accurate only in some geometrical arrangements. New generation of Finite Element Analysis software like EMS simulates high frequency phenomenon with much higher accuracy and is easy to use.
