“…Thus, it can improve the overall efficiency of the converter, prevent the load from affecting the power grid, and reduce the size and complexity of the power supply system, and is suitable for different loading conditions. Due to the above mentioned advantages, the applications based on LLC resonant converters have been developed at a burgeoning rate for over ten years, including an electric vehicle (EV) charging station [14][15] , laptop adapter [16] , liquid crystal display (LCD) TV power supply [17] , LED lighting driver [18] , battery charger [19] , and photovoltaic system [20] . The LLC resonant converter is mainly responsible for electrical isolation, high energy density, and soft-switching functions [21] , contributing to an increased product safety, low EMI and harmonic pollution, reduced product weight, and high efficiency.…”

Owing to the advantages of high efficiency, high energy density, electrical isolation, low electromagnetic interference (EMI) and harmonic pollution, magnetic integration, wide output ranges, low voltage stress, and high operation frequency, the LLC resonant converters are widely used in various sectors of the electronics-based industries. The history and development of the LLC resonant converters are presented, their advantages are analyzed, three of the most popular LLC resonant converter topologies with detailed assessments of their strengths and drawbacks are elaborated. Furthermore, an important piece of research on the industrial applications of the LLC resonant converters is conducted, mainly including electric vehicle (EV) charging, photovoltaic systems, and light emitting diode (LED) lighting drivers and liquid crystal display (LCD) TV power supplies. Finally, the future evolution of the LLC resonant converter technology is discussed.
