N2 - Three-phase impedance source inverters can be modulated using many modulation schemes, which are basically classified into two categories: three-phase-leg shoot-through-based (3P) and single-phase-leg shoot-through-based (1P) modulation schemes. These different modulation schemes have been comprehensively reviewed in Part I. Hence, in this paper, a comparative assessment among these different modulation schemes is introduced using the conventional Z-source inverter (ZSI). In this comparison, the ZSI voltage gain and stresses, current stresses, effective switching frequency of its different parts, spectrum of its output voltage, and switching losses are considered for each modulation scheme. Such comparative assessment introduces an effective benchmark for the researchers in order to determine the differences among these various modulation schemes, and easily select the appropriate one for their application. Finally, the state-of-the-art modulation schemes are experimentally assessed using a 3-kVA three-phase ZSI, where the shown results are consistent with the presented discussions and comparisons.
