14:00 Design of Magnetic Components for High Power Converters
M.Sc. Tomás Pagá, Enerdrive, Zürich, Schweiz
Filter chokes and transformers for high power converters, ranging from hundreds to thousands of kW, are commonly one of the most costly and difficult components to design. Desired electrical performance and tight restrictions in weight, volume and cooling represent a challenging compromise for the designer. In this seminar we address topics from how to specify the components for outsourcing to how to get deep inside the detailed design. References, test results and failure examples from real cases are presented. The seminar will be based on a design case, where the main design problems for each step will be addressed. Analytic, Finite Element Method and Circuit Simulation tools will be used during the design. Losses calculation and measuring are treated in detail. Losses produced by the switching high frequency components are often miscalculated resulting in poor thermal performance. High frequency losses curves of laminated magnetic steel are commonly not available from the suppliers, so the designer faces with the need of high frequency losses measuring methods. Losses measurement error sources, like low power factor and angle errors, are explained in detail and methods to overcome those issues will be discussed. Additional sources of losses due to winding resistance, skin/proximity effect and fringe flux on the air-gaps will also be addressed. Finite Element modeling of high frequency winding losses will be used for the analysis. Finally, cooling methods and mechanical design considerations for robustness and acoustic noise reduction are
