AB - This paper presents a comparative analysis of four LLC resonant converter topologies (HBLLC, FBLLC, HBILLC, and FBILLC) for EV charger applications. The operating principles and voltage gain characteristics of each topology are analyzed based on the fundamental harmonic approximation, and key design parameters such as resonant inductance, magnetizing inductance, and switching frequency are derived. All converters are designed for a rated power of 6.6 kW with an input voltage of 380V and an output voltage range of 200V–450V. Their performance is compared in terms of power loss, efficiency, and power density using PLECS simulation results. This study compares the performance of various LLC converter structures to derive an optimal topology that achieves high efficiency and power density over a wide output voltage range required for EV charging systems.
