DIAMET CORPORATION List of Products and Services

This method uses a low permeability powder core "MBS" in the main transformer and adopts ON-ON / ON-OFF operating modes, enabling the miniaturization of magnetic components to about 1/3 and the power board size to about 2/3 compared to conventional circuits (according to our estimates). In addition to achieving space-saving in the power circuit without increasing the operating frequency, further miniaturization is possible by increasing the operating frequency. It is possible to achieve a compact and high-efficiency DC-DC converter without using SiC or GaN, while still using general-purpose Si. 【Features】 ■ Realizes miniaturization and high efficiency of DC-DC converters (power circuits) ■ By suppressing the amplitude of the excitation current, it also achieves a reduction in ΔB (change in magnetic flux density) and the resulting low loss ■ The output ripple current is approximately halved compared to conventional technology, allowing for a reduction of the output capacitor by half ★ We are currently offering a simple calculation tool.

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.

This method uses a low permeability powder core in the main transformer and adopts ON-ON and ON-OFF operating modes, enabling the miniaturization of magnetic components to about one-third and the power board size to about two-thirds compared to conventional circuits (according to our estimates). Additionally, the reduction of the amplitude of the excitation current leads to a decrease in ΔB (change in magnetic flux density), achieving low loss. Instead of increasing the operating frequency to achieve miniaturization, we contribute to space-saving in power circuits by innovating the handling of magnetic components. It is also possible to further miniaturize by increasing the operating frequency. High efficiency and compactness of DC-DC converters can be achieved without using SiC or GaN, while still utilizing general-purpose Si. We offer our unique powder core "MBS" series suitable for this circuit method. 【Features】 ■ Miniaturization and efficiency improvement of DC-DC converters are achievable. ■ ΔB (change in magnetic flux density) can be suppressed, enabling low loss. ■ The output composite ripple current is about half that of conventional technology, allowing for a reduction of output capacitors by half. ★ We are currently offering a simple calculation tool.
