Abstract	Efficiency improvement has become a hot topic in grid-connected inverters (GCI). In single-phase single-stage cascaded multilevel GCIs (CM-GCI), the level number of the inverter output voltage will change with the variation of the DC supply source generation power. This results in significant changes of switching losses and changes in the total harmonics distortion (THD) of the grid current. In this study, the switching losses and the current THD of CM-GCI are derived under variable DC voltage. The theoretical analysis indicates that switching losses will increase with increasing DC voltage while the current THD will be reduced. Furthermore, on the basis of the derived expression of the current THD and taking the special grid current THD standards as design criteria conditions, an European efficiency enhancement scheme with adjusting carrier frequency in real time is proposed. Detailed experimental results including the constant and variable carrier frequency schemes are given and compared with each other to verify the accuracy of the theoretical analysis results and the validity of the proposed efficiency enhancement scheme.
