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.

**Principle of Miniaturization for the New Circuit Technology "Isolated TriMagiC Converter (TM)"** The main transformer in our proposed circuit technology "Isolated TriMagiC Converter (TM)" features a structure where the input winding is directly applied to the smoothing choke coil of the conventional current doubler rectification. This allows for the dual 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. **Other Features** - Compared to typical circuit boards for a 1.6kW output DC-DC converter, approximately 30% miniaturization is achieved with similar efficiency (using our functional evaluation prototype). - DC-DC circuit topology with "ON-ON & ON-OFF" operating modes. - Particularly suitable for applications where miniaturization is highly demanded. - We can propose circuit topologies tailored to specifications and provide suitable transformers and magnetic components (cores) for those circuits. *For more details, please refer to the documentation.
