Abstract
From the point of building bidirectional power flow path for the energy storage element (ESE), this paper proposes a general approach to develop multi-port converters (MPCs) by connecting the ESE-centric H-bridge cell with source or load of the classic converter. Six configurations are presented by investigating the connecting principles between H-bridge and the source or load of the classic converter. Derived by combining the six configurations with the classic converter, the obtained MPCs feature single-inductor and single-stage power conversion among the ports. The operating characteristics and port voltage restriction of MPCs are analyzed and compared. Experimental results of the proposed MPCs, named L-3-buck/boost, are presented to verify the analysis results.
