A Three Port Converter (TPC), which can interface with renewable sources, storage elements and loads simultaneously, is a good candidate for the solar power systems. My aim is to produce constant output power in all times (day& night). So I used three port full bridge converters in solar electrical energy. A systematic method for generating Three Port Converter topologies from Full Bridge Converters are described here. By using this systematic method, a novel full-bridge TPC (FB-TPC) is developed for renewable power system applications which feature simple topologies and control, a reduced number of devices and single-stage power conversion between any two of the three ports. This method splits the two switching legs of the FBC into two switching cells with different sources and allows a dc bias current in the transformer. The FB-TPC consists of two bidirectional ports and an isolated output port. The primary circuit of the converter functions as a buck-boost converter and provides a power flow path between the ports on the primary side, while the third port provides the power balance in the system ports. The full bridge three port converter is designed and simulated using MATLAB/SIMULINK. The output parameters such as output voltage, current and power were obtained.
