A Novel LLC Resonant Converter Circuit-Input Parallel Output Series Subside Resonant LLC Resonant Converter

open access: yesJournal 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
