Guo X, Xu D, Wu B. Three-phase seven-switch inverter with common mode voltage reduction for transformerless photovoltaic system. In: Proc. of the annual conference of the IEEE industrial electronics society. 2015.
In this literature, a common-ground configuration has been presented as an effective solution for the leakage current problem; a few examples of common-ground inverters have been discussed in these papers. However, a large number of common-ground converters have already been presented in the literature.
All other inverters belonging to this category can offer three voltage levels; Among the inverters offering five voltage levels, the inverter in uses a fewer number of switches than the other inverters introduced in [51,53].
Furthermore, the proposed inverter is comprehensively compared with other five-level TIs to show its superiority. Finally, a laboratory prototype is developed and tested to validate the practical viability of the proposed configuration. 1. Introduction
