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 ...
