Achromat is at the forefront of developing magnetic inductor cores and their materials for power conversion devices, which are crucial components in electric and hydrogen vehicles, AI Server and many kinds of electrical applications. These inductor cores play a vital role in electronic circuits, responsible for controlling, storing, and transmitting electrical energy. Achromat has a lineup of essential cores that can meet the latest technical requirements for higher efficiency and supplies products of the highest quality. The basic core materials provided by Achromat are as follows. 1. Ni based (Fe-Ni) Characterized by its high magnetic flux density, it is ideal for applications needing high energy storage and low core losses, providing a balance between cost and performance. 2. Ni-Free (Fe-Si) Fe-Si offers high saturation flux density and low core loss, making it a cost-effective solution for many power conversion applications. 3. Low Nickel (Hybrid materials) These materials reduce the nickel content to 20-30%, offering a cost advantage to customers while providing relatively superior DCB and core loss characteristics. This can replace designs that previously used initial HF materials. 4. Sendust (Fe-Si-Al) Known for its excellent energy storage capabilities and low core loss, it is particularly effective in reducing electromagnetic interference (EMI) and is commonly used in power inverters and converters.
