Magnetically Coupled Impedance-Source Inverters [PDF]
IEEE Transactions on Industry Applications, 2012 Z-source inverters are a new class of inverters proposed with output voltage or current buck-boost ability. Despite their general attractiveness, there are some present limitations faced by existing Z-source inverters, most of which are linked to their requirement for low modulation ratio at high input-to-output gain and the presence of an impedance ...
