This paper introduces a three-port current-fed converter with isolation transformer operating in high frequency and bidirectional power stream. Port I is nourished by a battery bank, port II utilizes a lot of photovoltaic (PV) modules and port III is associated with a dc interface. The topology utilizes three singlestage H-connect cells in the essential side and a three-stage H-connect converter in the optional one. Highfrequency seclusion is guaranteed by single-stage transformer associated in an arrangement. The proposed converter also fed with PI based control technique which offers the output voltage control. The three phase three port converter with PI based control has been proposed and the results experimented in MATLAB/SIMULINK and it is compared with the conventional circuit.
