Three-phase DC-bypass topologies with reduced leakage current for transformerless PV systems

2015 IEEE Energy Conversion Congress and Exposition (ECCE), 2015
Leakage current reduction is one of the most important issues for transformerless PV grid-connected inverters. Many interesting single-phase topologies have been reported to reduce the leakage currents. However, three-phase PV inverter topologies with reduced leakage currents are not received much attention.

Novel single-phase transformerless inverter based on the freewheeling loop separation for PV systems

2016 IEEE 8th International Power Electronics and Motion Control Conference (IPEMC-ECCE Asia), 2016
Transformerless inverters are widely used in low-power single-phase grid-connected PV systems, because of its high efficiency, low price, light weight, small volume. However, it is a big problem that the dangerous leakage currents appear without using transformers.
