Abstract
Advanced magnetic materials are extensively considered for the development of high-power high-frequency magnetic links (HFMLs) for evolving power conversion technologies. For grid synchronization of distributed renewable energy sources (RESs), multi-winding HFMLs (MWHFMLs) are becoming popular nowadays. A literature survey reveals that most of the designs of HFMLs incorporate concentrated secondary and primary windings. In this paper, the mathematical model of a 1 kW, 20 kHz MWHFML is presented. Also, the MWHFML is designed with ANSYS/Maxwell software for electromagnetic analysis. The power transfer and other electromagnetic performances of the proposed MWHFML are evaluated and compared considering two types of secondary winding topology, i.e., concentrated and interleaved windings. The analysis shows, that approximately 27% more electrical power can be transferred from multiple primary windings to a single secondary winding with an interleaved topology. Two reference core geometries have been considered to apply the proposed interleaved winding topology. It is envisaged that the proposed design of MWHFML with interleaved winding will play a significant job in the development of competent power converter technologies for future grid-integrated RESs.
