Nowadays, the use of transformer‐less single‐phase inverters is widespread for domestic photovoltaic applications due to the high efficiency that can be obtained. Here, three similar topologies of transformer‐less inverters are compared to highlight their differences. They are the full‐bridge, the H5, and H6 inverters. The analysis considers the efficiency, the leakage current, and the quality of the output current when different modulation techniques are adopted. The experimental tests are carried out in the same operating conditions and with the same experimental set‐up, thus emphasising the advantages and drawbacks of each topology.
