Large-signal stability conditions for semi-quasi-Z-source inverters: switched and averaged models
, 2013 The recently introduced semi-quasi-Z-source in- verter can be interpreted as a DC-DC converter whose input- output voltage gain may take any value between minus infinity and 1 depending on the applied duty cycle. In order to generate a sinusoidal voltage
