Sensitivity analysis of transformerless PV inverter topologies to physical variations of power devices
Transformerless (TL) topologies are employed in 1φ PV inverter topologies due to their small size and low weight. Avoiding the grid side transformer requires the modulation technique and the basis topology to be accordingly changed in order to mitigate dc current components in the grid side and the leakage current to ground. This paper carries out a sensitivity analysis of selected TL topologies. This analysis investigates the impact of parameter variations of the employed semiconductor devices and detects the device which affects the most the overall efficiency. As a result, relevant info for engineers selecting the most suitable power devices for the implementation of a certain TL topology is provided.
