Terminal voltage analysis for the transformerless PV inverter topologies in a single‐phase system [PDF]
IET Renewable Power Generation, 2019 This study presents an analysis of the terminal voltage of the basic photovoltaic (PV) inverter topologies available in the literature. The presented analysis utilises the switching function concept. Use of switching function in the analysis enables the inclusion of the effect of the pulse‐width modulation technique or the switching strategy on the ...
