How are SiC and GaN Catching up to Planar Magnetics?

Focus:

This presentation pulls together information on planar magnetics technology and power supply and power semiconductor technology trends to explain why planar magnetic components are well suited for use with the emerging gallium nitride (GaN) and silicon carbide (SiC) power semiconductor devices that are being developed and applied in advanced power supply designs. The characteristics and benefits of planar magnetic structures are given the most attention here. But there are also sections discussing power magnetics design objectives, PSMA and ARPA-E data on technology trends (particularly power supply efficiency), an actual power converter reference design using GaN power devices together with planar magnetics, and the significance of gallium nitride power devices and SiC Schottky diodes.

What you’ll learn:

• How to understand the characteristics and benefits of planar magnetic components that make them well suited for use with emerging GaN and SiC power devices

Notes:

This presentation was given in an industry session at APEC 2014.
