Pulse Electronics Exploiting Integrated Planar Magnetics

In today’s high-density switched-mode power supplies, transformers and inductors are the main contributors to their size, weight and volume. Magnetic integration is a solution where two or more magnetic elements are combined into a single structure. By proper phasing of the windings and the placement of an air gap in a specific location in the flux path, integration allows more efficient use of the cross sectional area of the transformer or inductor core, resulting in a reduced need for core material.
