Modulation Techniques to Eliminate Leakage Currents in Transformerless Three-Phase Photovoltaic Systems

In some photovoltaic (PV) applications, it is possible to remove the transformer of a system in order to reduce losses, cost, and size. In transformerless systems, the PV module parasitic capacitance can introduce leakage currents in which the amplitude depends on the converter topology, on the puls...
