With the increasing adoption of renewable energy and the proliferation of EV fast-charging stations, the demand for high-power power supplies is growing.
Transformers used in these power supplies are expected to be more compact, efficient, and generate less heat. Ferrite materials are integral to transformer products. However, core losses (iron losses) in ferrite cores can vary significantly depending on the core size, operating frequency, and load. Therefore, selecting the optimal ferrite material is a crucial aspect of transformer design.
This article introduces the features of the PEL95 material, developed specifically for high-power applications, and key considerations for its use.

Transformers used in power supplies are expected to be smaller, more efficient, and generate less heat. Ferrite materials are used in transformer products, but the core loss (iron loss) can vary significantly depending on the size of the ferrite core, the operating frequency, and the load. Therefore, selecting the optimal ferrite material is a key point in transformer design.

In conjunction with the increased use of GaN semiconductor, which can operate a high frequency, higher frequencies for switching power supplies have become feasible. Ferrite materials are used in transformer products, but core loss (iron loss) varies greatly depending on the driving frequency, and they are key components in transformer design. This article presents information on the features of PC200 material, which was developed by using GaN, and key points concerning its use.
