Abstract: A novel high-frequency isolated dual three-level neutral point clamped (NPC) half bridge (DTHB) CLLC bidirectional resonant DC-DC converter with a symmetric series LC resonant network is proposed for a transformerless high power cascaded multi-level converter. This converter combines the advantages of bidirectional three-level half-bridge converters and the LC resonant converter and can be used in high power high voltage applications. This paper analyses the operating modes and characteristics of the equivale…
