A 300-kHz 6.6-kW SiC Bidirectional LLC Onboard Charger
IEEE Transactions on Industrial Electronics, 2020The reverse LLC voltage gain is lower than unity. The dc-link voltage is then lower than the peak grid voltage so that the buck type dc–ac converters cannot be grid-tied directly, which causes the LLC reverse operation difficult in bidirectional ...

Three-Phase LLC Battery Charger: Wide Regulation and Improved Light-Load Operation
IEEE Transactions on Power Electronics, 2021Three-phase LLC resonant converters can handle much higher power compared to half-bridge and full-bridge LLC converters, which makes them suitable for levels 2 and 3 battery charger applications.

A Structure-Reconfigurable LLC Resonant Converter With Wide Gain Range
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2023In this article, a structure-reconfigurable LLC (SR- LLC) resonant converter is proposed for wide output voltage applications. The converter can operate in half-bridge mode or full-bridge mode by modulating the driving signal of the switches.
