The Database of High-Frequency Miniaturized Power Modules focuses on zero-voltage switching (ZVS)/zero-current switching (ZCS) full-resonant soft-switching topologies that can exploit the on-state performance of GaN power switching devices, along with their driving and control technologies. The objectives include reducing the electrical stress on GaN devices, eliminating or lowering switching losses, and cutting down the conduction losses of switching tubes during high-frequency switching operations. Aiming at the problem of increased magnetic component losses under high-frequency conditions, this work also investigates loss prediction methods for magnetic components applicable to high-frequency high-density power modules. With the assistance of accurate Maxwell-3D simulation tools, more precise eddy current loss prediction models for magnetic cores and windings in high-frequency magnetic components are developed. Additionally, this study explores loss optimization design approaches for high-frequency high-current transformers, novel high-efficiency high-frequency transformer structures, and efficiency optimization methods for multi-magnetic-component integration of high-frequency transformers, to reduce winding eddy current losses and enhance the efficiency and power density of the power modules. The dataset contains detailed research activity records and basic data generated during the implementation of Task 4, developed technical reports, filed patent applications, published academic papers, and test reports issued by qualified third-party testing institutions, among other relevant materials.
