Full bridge three port converter power flow control using fuzzy logic controller

The concept of using renewable energy sources usage is increasing day by day but there is a limitation of it as we cannot use standalone renewable system. With standalone systems, the storage devices are used for backup power. The load and sources are interfaced by the power converters. In this paper, a new three port converter is analyzed. The analyzed converter is derived from full bridge converter which was split into two different cells; each cell is interfacing the input source. A cell is composed of two switches. The input to each switch in cell is inverted of other switch in a cell. A transformer is used between input and output port to provide isolation. The Fuzzy logic controller is used to control the power flow in three-port converter which interfaces a PV panel, a battery and an output port to the load. The difference between two powers, PV panel power and demanded power, is used as input for fuzzy logic controller and the output of fuzzy logic controller offers two signals: the first signal is for the first cell while the second signal is for the second cell; Simulation results, concerning the fuzzy control of power flow in various circumstances where obtained in MATLAB/Simulink.
