Abstract
In high-power applications,the three-phase interleaved LLC resonant converter can effectively reduce the single-phase current stress and the output ripple through the interleaved parallel connection technique,and minimize the size of the output filter capacitor to further improve the power density.The circuit mathematical model for the three-phase interleaved LLC resonant converter is constructed,the key parameters are designed,and the equivalent circuit model is adopted for the theoretical analysis.Mean while the heat dissipation optimization of the magnetic components is taken into account to ensure the conventer's reliable operation in high-temperature environments.Finally,a 60 kW three-phase interleaved LLC resonant converter prototype is designed and constructed.Through experimental tests,the effectiveness of the proposed scheme is verified,and providing a reference for the design and optimization of LLC resonant converters in high-power applications.关键词
