摘要
A single-stage photovoltaic grid-connected inverter, which comprises a DC-AC inverter circuit having an output connected to an alternating-current grid, and also comprises a DC-DC boost circuit connected in series between a photovoltaic array and the DC-AC inverter circuit, and a parallel circuit of bypass elements, wherein the rated power capacity Pdc of the DC-DC boost circuit is less than the rated power capacity Pac of the DC-AC inverter circuit.
