Abstract
This paper presents a three-port soft switching dc-dc converter topology based on the bidirectional version of the three-state switching cell (3SSC) and dual active bridge (DAB), feasible to interconnect battery banks with a dc link and photovoltaic panels. The converter features high voltage gain and current reduced stress in the converter primary switches. All active switches are designed to operate in Zero Voltage Switching (ZVS). The theoretical analysis and experimental results a 2 kW prototype are presented. The experimental results are presented in two modes: Mode Discharge Battery Bank (MDBB) and Mode Charge Battery Bank (MDBB). The maximum efficiency in MDBB is 96% and in MCBB is 95.5%.
