| Abstract: | Based on the analysis on energy storage, loss, tansmission and operation characteristic curve of magnetic core of high frequency switching power-transformer, applying B-H curve of magnetic core material and Q value and combining LTCC technology, we propose a complete design principle and method for LTCC high frequency switching power transformer. Taking the flyback high frequency switching power transformer as a example, the main aspects of desigh is described. Based on the Maxwell 2D/3D field simulation, the winding structure is revised and core parameter is optimized, and a reasonable design scheme is obtained for the given example. |
