Abstract:

The stand-alone renewable power system with three-port converter features high efficiency, high power density, high reliability, small size and low cost. Analyzing power flow among the ports, it is found that a three-port converter (TPC) can be treated as a dual-output converter from the point of primary source and as a dual-input converter from the load, respectively. Begin with reconstructing the power flow paths, both combined and integrated non-isolated TPC (NI-TPC) topologies are proposed. The topology generation principles and methods are given with a series of NI-TPC topologies presented. The TPCs developed features single stage conversion between any two of the three ports. Operational mode analysis and experimental results of one of the proposed NI-TPC are given to verify the analysis.
