The previous generation of hybrid core design with 3 gaps for power chokes has been verified to be able to improve saturation current with even lower core loss than the conventional ferrite framework. However, the size issue in comparison and benchmark to alloy powder cores limits the power density. In this session a state-of-the-art heterogeneous core framework and the performance of power boost effect are presented. Unlike alloy powder cores, the advanced heterogeneous design can be easily applied to the core geometry with great complexity to suit your specific requirements and with highly satisfactory C/P value.
