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
