Analysis of an LLC–DAB integrated DC–DC converter topology with low loss and low cost
IET Power Electronics, 2023 This paper proposes an LLC‐DAB integrated high‐frequency isolated DC–DC converter topology structure to reduce the loss and cost of the DC power distribution system. Furthermore, the complexity and efficiency of the system also can be improved.

Analytical model for LLC resonant converters in operation below resonance
e & i Elektrotechnik und Informationstechnik, 2023 AbstractElectric cars are a great opportunity for reducing greenhouse gas emissions caused by transportation. High-power chargers are required to charge electric vehicles in a reasonable amount of time and considerably increase the driving range. As these high-power chargers currently need to be isolated with respect to the grid, the LLC converter ...

Journal of Physics: Conference Series, 2020 Abstract At present, LLC resonant converters are mostly used in step-down situations. The reason why LLC resonant converters are not used in high step-up situations is that parasitic parameters caused by high turn-to-turn ratio of transformers affect the circuit and the large current stress of switching devices and resonant components on

LLC Resonant Converter as a Current Source Using Simple Trajectory Control
Energies, 2023 This paper discusses a simple method for controlling an LLC resonant DC-DC converter using a state space trajectory based on a linear combination of the voltage across the capacitor and the current through the inductance in the series resonant tank.
