LLC resonant converter design for bendable power converter
2016 IEEE Applied Power Electronics Conference and Exposition (APEC), 2016In this paper, a design approach of LLC resonant converter with bendable transformer is presented. First, the electrical parameters of the LLC resonant converter are calculated based on the first-harmonic-approximation (FHA) equivalent circuit. Second, the bendable transformer design approach based on bendable transformer model gives the physical ...

Ceramic capacitor controlled resonant LLC converters
2018 IEEE Applied Power Electronics Conference and Exposition (APEC), 2018The possibility of applying standard commercial ceramic capacitors for controlling a resonant LLC converter was studied analytically and experimentally. Using a two serially connected ferroelectric capacitors assembly, experiments were run on a mockup of an LLC converter that was switched at 90kHz to a power level of 5W.

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.
