In recent years, due to energy crisis, renewable energy distributed power generators, such as wind turbine, photovoltaic (PV) cell, fuel cell, and thermoelectric generation modules, are becoming more and more popular in industrial and residential applications. Many renewable energy such as PV cell, fuel cell and thermoelectric generation can only output dc voltage. So an inverter interface has to be utilized for grid-connected applications. So many inverter topologies have been proposed and reviewed recently like as Z-source proposed inverter. In this proposed semi-Z-source inverters for a single-phase photovoltaic (PV) system. With low cost and doubly grounded features. These semi-Z-source inverters only two active switches. To achieve the same output voltage as the traditional voltage-fed full-bridge z-source inverter. The input dc source and the output ac voltage of the semi-Z-source inverter share the same ground. Thus lead into less leakage ground current advantages over other non-doubly grounded inverters.
