Abstract
Photovoltaic source (PV) has become the most promising DC sources of the future. We use inverter to convert the dc output of Solar cell to AC in order to utilize it for AC appliances. But the traditional inverters operate in either buck mode or boost mode not in buck-boost mode. Also traditional inverters provides dead band which causes distortion in the output current. The defects of conventional inverters are conquer in the impedance source (Z- Source) inverter. The impedance network injected between the input DC source and inverter six switches will offer the advantage of boosting the DC voltage. Through the impedance network the inverter is capable to buck-boost the input voltage. The elimination of dead band reduces the output current distortion and improves the efficiency.
