Abstract: A comprehensive mathematical modeling and control design for an isolated multi-port DC/DC converter for photovoltaic (PV) generation systems is discussed in this paper. The adopted converter is a modified flyback converter consisting of three ports, namely, a photovoltaic (PV) module input port, a bi-directional battery port, and an isolated output port. The output port is receiving its demanded power without any interruption, while the power extracted from the PV module is maximized adopting a maximum power point tracking (MPPT) controller. Moreover, to improve the overall efficiency of the system, synchronous rectification switches are used on the secondary side of the isolation transformer. Set of simulations using MATLAB/Simulink are done to show the effectiveness of the proposed converter under different operating conditions.
