How Planar Magnetics Help Solve Power Density, Thermal, and Packaging Challenges
One of the major considerations in power systems design is selection of magnetics, specifically, transformers that can support the required current, frequency, and size objectives. Planar magnetics are a low-profile option for many systems where SWaP (size, weight and performance) is a concern. These components use magnetics and packaging with a flat profile, involving windings that effectively stack on each other while wrapping around a large cross-sectional area. This provides very strong coupling to the magnetics core, which keeps magnetic flux confined within the body of the component package.
