Ultra-compact DC-DC circuit technology Insulated Tri-Magic Converter (TM)

Daiyamet Co., Ltd. (Headquarters: Higashi-ku, Niigata City, President: Hiroshi Iii) will exhibit at the "TECHNO-FRONTIER 2026 41st Power Supply System Exhibition" held at Tokyo Big Sight from July 15 (Wednesday) to 17 (Friday), 2026, showcasing the isolated DC-DC converter circuit method "TriMagiC Converter (TM)" that simultaneously achieves high power, high conversion efficiency, and miniaturization. At this exhibition, we will display prototype boards of 1.6kW and 3.3kW isolated DC-DC converters using the TriMagiC Converter (TM) circuit method, as well as introduce a lineup of pressed powder cores for transformers and resonant coils. Since last year, we have expanded our product lineup and will propose magnetic materials suitable for various applications, including high permeability and low loss materials. Additionally, we will showcase a mock-up of the PoL (Point of Load) converter for AI servers, which is being developed in collaboration with the Yamamoto Masayoshi Laboratory at the National Institute of Technology, Nagoya University. By viewing the actual size, visitors can experience the potential for high power density and miniaturization required for next-generation power supplies.

Daiamet Co., Ltd. will exhibit at the "TECHNO-FRONTIER 2025 40th Power System Exhibition" held at Tokyo Big Sight from July 23 (Wednesday) to July 25 (Friday), 2025. At this exhibition, we will introduce various prototype boards and core products, focusing on our unique magnetic material "Powder Core (MBS)" combined with circuit technology, featuring the new insulated DC-DC converter "TriMagiC Converter." Particularly noteworthy is the prototype unit achieving a conversion efficiency of 97.2%, which will be unveiled for the first time, with a power output of 1.6kW. Additionally, we plan to introduce the PoL converter, which we have recently begun joint research on with Nagoya University. Furthermore, during the exhibition, our senior advisor and developer, Mitsuaki Fujimoto, will provide a technical explanation of the new technology "TriMagiC Converter" in a seminar for exhibitors. This seminar will clearly present the technology of insulated DC-DC converters that achieve unprecedented miniaturization and high efficiency through the use of magnetic cores with low permeability and high saturation magnetic flux density, covering the background of development, operating principles, and prototype examples. We sincerely look forward to your visit.

Daiamet Co., Ltd. will exhibit at the "Automotive Technology Exhibition 2025 YOKOHAMA," which will be held at Pacifico Yokohama from May 21 (Wednesday) to May 23 (Friday), showcasing our latest technologies in sintered machine parts and sintered oil-impregnated bearings, as well as our new insulated DCDC converter circuit technology "TriMagiC Converter (TM)" that simultaneously achieves high power, high conversion efficiency, and miniaturization. The "TriMagiC Converter (TM)" utilizes our proprietary magnetic material "Powder Core (MBS (TM))" for transformers and resonant coils, combined with our uniquely developed high-performance insulated DCDC converter circuit technology, resulting in significant miniaturization and efficiency improvements compared to conventional circuits. We will display a circuit board (prototype) equipped with this technology at the venue. Additionally, we plan to showcase a thin motor, the "Axial Flux Motor," which also applies the Powder Core (MBS (TM)) and achieves both high torque and high efficiency. This motor is a next-generation type expected to be applied in electric vehicles (EVs) and industrial robots. We sincerely look forward to your visit.
