A review on LLC Resonant Converter
2016 International Conference on Computation of Power, Energy Information and Commuincation (ICCPEIC), 2016Resonant Converters have wide applications as they can produce a high voltage. Also these converters can reduce the switching losses by operating at Zero Current Switching and Zero voltage switching states. Series Resonant Converter can be used for low output current and Parallel Resonant converter can be used for high output current applications ...

Synchronous Rectification LLC Series-Resonant Converter
APEC 07 - Twenty-Second Annual IEEE Applied Power Electronics Conference and Exposition, 2007The primary goals in use of half-bridge LLC series-resonant converter (LLC-SRC) are high efficiency, low noise, and wide-range regulation. A voltage-clamped drive circuit for simultaneously driving both primary and secondary switches is proposed to achieve synchronous rectification (SR) at switching frequency higher than the dominant resonant frequency.

This chapter studies the LLC resonant converter operation in different modes. First harmonic approximation (FHA) is used to obtain the main converter characteristics in steady-state, including the dc voltage static gain. The obtained equations and curves are used to design circuit parameters and predict performance, which is verified through numerical ...
