Miniaturizing the power supply board to 2/3! New circuit technology for improving efficiency with general-purpose Si.
【Technical Data Presentation】Reducing costs while miniaturizing and improving efficiency without SiC/GaN. "Simple Calculation Tool" available for design assistance!
Solving issues such as "limitations of substrate area" and "cost increase due to SiC adoption." Our unique operating mode reduces magnetic component size by one-third without increasing frequency. We achieve dramatic downsizing while suppressing heat and noise. 【Challenges and Applications We Can Address】 ◎ Space Constraints: Reducing substrate area by two-thirds and magnetic components (such as transformers) by one-third (for applications like in-vehicle chargers, robotic joints, and 1U-sized communication boards). ◎ Cost Control: Achieving high efficiency using general-purpose silicon without relying on expensive SiC/GaN. ◎ Heat and Noise Mitigation: Halving ripple current and reducing magnetic flux density (ΔB) for low loss and low noise. 【Features of Our Unique Technology】 Adopting low permeability powder core "MBS" with "ON-ON / ON-OFF" modes. By suppressing the amplitude of the excitation current, we have made it possible to minimize transformers and capacitors. ★【Free Offer】Simple Calculation Tool & Technical Materials We are distributing a tool that allows you to instantly estimate "how much smaller it can get under your conditions."

basic information
**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.
