Full Bridge Three Port Converter for Renewable Energy Resources with P & O MPPT Technique

摘要

C A novel full-bridge TPC (FB-TPC) is developed for renewable power system applications which feature simple topologies and control.The proposed 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.It can adapt to a wide source voltage range, and tight control over two of the three ports can be achieved .To harvest maximum possible energy from the system, a modified Maximum power point technique (MPPT) is used.Furthermore, Experimental results verify the feasibility and effectiveness of the developed FB-TPC.
