Design of an integrated magnetics structure for LLC resonant converter
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017This paper, we propose IM (Integrated Magnetics) structure for LLC resonant converter. The IM technique can combine several components into one magnetic core, plus, utilizing a planar magnetic core is a suitable device to achieve high power density. Therefore, it can achieve high power density in Switch Mode Power Supply (SMPS) because the total volume

LLC and LCC Analysis and Comparison of Resonant Converters
2020 35th Youth Academic Annual Conference of Chinese Association of Automation (YAC), 2020In this paper, we adopt variable frequency control strategy for resonant converters with LLC and LCC resonant structures, which work in the zero voltage switch (ZVS) region. Based on the fundamental wave analysis (FWA) method, we obtain some theoretical research results.

Digital control of a half-bridge LLC resonant converter
2012 15th International Power Electronics and Motion Control Conference (EPE/PEMC), 2012Recently, LLC resonant converters are gaining more and more interest in DC/DC conversion due to their high efficiency and power density. Usually, they are used in low power applications, i.e. in the range of few hundred Watt and with constant output load, however they are very appealing in high power and renewable energy applications as well as in many

LLC parallel resonant converter design by scaling the LC converter
IEEE Transactions on Aerospace and Electronic Systems, 1998An efficient and practical method for steady-state design of an LLC-type parallel resonant dc/dc converter (LLC-PRC) is presented. In general, the output characteristic curves of LLC-PRC can be obtained by multiplying the output curves of the LC-type parallel resonant converter (LC-PRC) by a ratio of the parallel and series inductances.

IMPLEMENTATION OF 480W LLC RESONANT CONVERTER
2019This study presents the design of an LLC resonant converter as using the leakage inductance of the transformer instead of the inductance in the resonance tank. With serial resonant characteristics, the power MOSFETs are conducted at zero voltage switching and secondary diodes are commutating under soft switching, so the switching power losses on the ...

Output Plane Analyses of LLC Resonant Converter
2020 IEEE Applied Power Electronics Conference and Exposition (APEC), 2020LLC resonant converters are popular for point-of-load (POL) DC-DC conversion in various applications due to its soft-switched characteristics, high operating efficiency and reduced EMI noise profile. In complex systems, modular structure is maintained by using POL converters in parallel to feed a high power load. Therefore, it is essential to model the
