a new configuration for power sharing of two z-source inverters

This paper presents a new structure to provide the ability for power sharing of two z-source inverters. according to the operation principles of z-source inverters, only one input source supplies the circuit, which is a limitation particularly for the stand alone systems feeded by limited output power such as photovoltaics and feul cells. furthermore; if one source fails to supply, the load can't be supplied. this paper covers those via interconnection of impedance network of two z-source inverters. the operating principles of the proposed topology for the stand-alone and power sharing conditions are described and the relations are derived. the topology is simulated, which the results verify the theoretical analysis and well performance of the system.
