Three-level topology is considered as the best configuration in high-power solar inverter systems. In addition to lower switching losses and drain-source voltage requirements, EMI can also be reduced as the conducted EMI is mainly linked to the current ripple. Moreover, a three-level system can provide better sinusoidal voltage waveform.
Three-level inverter has been widely used in the middle and high voltage large capacity AC speed regulating fields, since its output has higher power quality, lower harmonic contents, better electromagnetic compatibility, lower switching losses, and other advantages.
Moreover, higher boosting is needed for grid-connected low-voltage PV modules to match the required AC voltage in the grid . The three-level neutral-point-clamped quasi-Z-source inverter (3L-NPC-qZSI) is mostly preferred because it offers improved power quality which can be supplied to the grid .
