【Technical Data Presentation】Reducing costs while miniaturizing and improving efficiency without SiC/GaN. "Simple Calculation Tool" available for design assistance!

**Principle of Miniaturization** The main transformer in our proposed circuit technology, the "Isolated TriMagiC Converter (TM)," features a structure where the input winding is directly applied to the smooth choke coil of the conventional current doubler rectifier. This allows for the dual operation of both the transformer and the coil. As a result, conventional main transformers become unnecessary, reducing the total size of magnetic components to less than one-third, achieving miniaturization. We offer our unique powder core "MBS" series, which is suitable for this circuit method. We can also propose circuit topologies tailored to specific requirements, as well as transformers suitable for those circuits and provide magnetic components (cores). *For more details, please refer to the materials. Feel free to contact us with any inquiries.*

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.
