DC-DC converter circuit technology
New Compact Design Technology for DC-DC Converters（TriMagiC ConverterTM)
Achieving miniaturization of passive components in ON-ON converters necessitates increasing the operating frequency, but this also leads to a decline in power conversion efficiency. The new circuit topology proposed by our company, the isolated “TriMagiC Converter(TM),” replaces ferrite with our proprietary magnetic material “MBS,” which features low permeability, high saturation magnetic flux density, and low loss. Powdered cores are used for the magnetic components of the transformer and resonant inductor. Our prototype testing has confirmed that by utilizing “MBS” in an ON-ON & ON-OFF operating mode circuit, we can simultaneously achieve high conversion efficiency and significant size reduction—reducing the total volume of magnetic components to one-third of conventional designs while still handling high power. The isolated “TriMagiC Converter(TM) achieves miniaturization and high efficiency of Switched Mode Power Supplies without the use wide band-gap devices such as SiC or GaN, even utilizing conventional Si switching devices. Moreover, replacing conventional phase-shifted converters with this new topology is straightforward. This document provides an overview of the features of the new circuit topology.
