Partially isolated four port converter with combined PWM and secondary phase shift control

A partially isolated four-port converter is proposed in this paper for interfacing two renewable sources and a storage device with an load. This capable of achieving high power density because the effective sharing devices among input ports. Combined PWM secondary phase shift control employed to have decoupled flow management output side used at maximum tracking battery management. At side, Phase controlling voltage. The adopted allows primary switching legs be operated 1800 which results reduced current ripple working principle converter, its characteristics strategy are discussed. Working verified through simulation different conditions. Further, validate results, experimental 500W prototype also provided.
