[Exhibition Announcement] Unveiling the "TriMagiC Converter" that opens the future of compact and high-efficiency power supplies at TECHNO-FRONTIER!

DIAMET CORPORATION

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.

Date and time Friday, Jul 25, 2025
12:10 PM ～ 01:00 PM

Significantly miniaturized and made more efficient insulated DC-DC converters through ON-ON / ON-OFF operation modes [Simple calculation tool and technical materials provided].

【Exhibition Overview】 Date: July 23 (Wednesday) to July 25 (Friday), 2025 Venue: Tokyo Big Sight, West Exhibition Hall, Halls 3 & 4 (4-W36) On the day of the event, we will have prototype machines with 1.6kW and 3.3kW that demonstrate miniaturization. Additionally, on the 25th (Friday) at 12:10, we will hold a seminar. Developer Mitsuaki Fujimoto will explain the features and operating principles of this method in the Exhibitor Seminar (2) venue. 【Principle of Miniaturization】 The main transformer in our proposed circuit technology, "Isolated TriMagiC Converter (TM)," features a structure where the direct input winding is applied to the smoothing choke coil of the conventional current doubler rectifier. This allows for the combined operation of both the transformer and the coil. As a result, the conventional main transformer becomes unnecessary, reducing the total size of magnetic components to less than one-third, achieving miniaturization. We offer our unique powder core "MBS" series suitable for this circuit method. We can also propose circuit topologies tailored to your specifications, as well as transformers suitable for those circuits and provide magnetic components (cores). *For more details, please refer to the materials.
