Popis: With the feature of soft switching, LLC resonant converters present the advantages of high conversion efficiency and low electromagnetic interference that it is applicable to power converters. However, since the output current ripples are large, LLC resonant converters would require larger output capacitors to achieve the feature of high DC output quality. With the application of resonant circuits, the provided current shaping network has overcome the above drawbacks; however, there is still no design rule for resonant element parameters. For this reason, this study aims to develop a series of methods for the design of resonant element parameters and to seek for the optimal output current modification so as to achieve the purpose with the lowest output current ripples. The experimental results show that it can effectively reduce the output current ripples up to 20.4%, when the output is fully loaded.
