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.
