What is Planar Technology?

The demand for increased efficiency and power density in power converters is relentless.

In recent years it has driven the development of ever more efficient converter topologies and advances in power semi-conductors. These developments and the need for greater efficiency have switched much of the demand to magnetic components. But these too must keep pace with ongoing technological development. Thus it is imperative their design and manufacture must be innovative and of the highest possible quality. Planar technology from Planar Magnetics Limited produces high performance magnetic components that are ideal for most modern power converter topologies. Furthermore, it has been established that, in many applications, planar technology provides enhanced performance and valuable manufacturing benefits over conventional technology.

The magnetic and electrical benefits of planar technology and their contribution to more efficient magnetic components are well-documented.

• Low leakage inductance and low winding AC resistance are more easily achievable
• High consistency between components is assured. In addition, there are mechanical benefits that aid the development of more efficient power converter products.
• The low profile nature of the technology makes it ideal for many power circuit applications.
• The flat structure is better suited to heatsink mounting.
• High current connections can be made more easily.
• Pin positions can be more easily optimised to provide clearances only where they are required.
• Windings can be screened more easily.
