There is a strong trend in the photovoltaic inverter
technology to use transformerless topologies in order to acquire
higher efficiencies combining with very low ground leakage current.
In this paper, a new topology, based on the H-bridge with a
new ac bypass circuit consisting of a diode rectifier and a switch
with clamping to the dc midpoint, is proposed. The topology is
simulated and experimentally validated, and a comparison with
other existing topologies is performed. High conversion efficiency
and low leakage current are demonstrated.
