Recent Development in Ferrite Material for High Power Application [Passive Components]

The most recent ferrite development is illustrated in material and in core shape. The highest Bs material is in focus for high power, i.e., SiC-driven application in high power for motion, automotive, and traction application associated with midvoltage dc grid propagation and high power density. The high Bs is desired according to Snoek's law, and while Bs is predominately influenced by chemistry, the loss mechanism is crystallind with an investigation into its morphological nature and its processing parameters, i.e., the densification process. Another trend in large -sized core shapes, about 8 in in height and 4 in in width, is also described, overcoming challenges to deliver perfect artificial ferrite ceramic to fulfill the needs of newest developments in power electronics. Today, ferrite, after nearly 100 years of development, is manufactured with a capacity of about 500,000 metric tons per year for diverse industries. This recent innovation is rooted in Snoek's formulation. Both high power density and high power application requires high Bs characteristics. It is crucial to understand both the chemical composition and the morphology engineering process to fully comprehend the impressiveness of the artificial ceramics.
