The impedance network coupling the source to the inverter bridge allows boosting the input voltage through utilizing shoot - through states. The conventional PWM inverters' switching methods are also applied to the quasi impedance source Inverter - QZSI; the modulation index and the periods at which shoot - through occurs determine the RMS voltage of the inverter's output. The simulation and experimental results validate the design of the presented QZSI as a single stage inverter providing a satisfactory performance in grid connected applications ER -
