Flying-Capacitor-Based Hybrid LLC Converters With Input Voltage Autobalance Ability for High Voltage Applications PROJECT TITLE :Flying-Capacitor-Based Hybrid LLC Converters With Input Voltage Autobalance Ability for High Voltage ApplicationsABSTRACT:An advanced hybrid LLC series resonant converter with integrated flying-capacitor cell is proposed during this paper to enable the high step-down conversion within the high input voltage applications. The inherent flying-capacitor branch in the first side can effectively halve the primary switch voltage stress compared with the 0.5-bridge LLC converters. And therefore the input voltage will be shared equally and automatically between the 2 series [*fr1]-bridge modules while not additional balance circuit or management strategies because of the engineered-in flying-capacitor cell. Moreover, the inherent soft switching performance throughout wide load vary that exists in the LLC converters continues to be kept to scale back the switching losses, which ensures the high efficiency. Besides, the proposed converter will be extended to more decrease the switch voltage stress by using stacked association. Finally, a 500 ∼ 640 V-input 48 V-output 1 kW prototype is made and tested to verify the effectiveness of the proposed converter. The results prove that the proposed converter is a wonderful candidate for the high input voltage and high step-down dc/dc conversion systems. Did you like this research project?
