Abstract
A DC-AC converter, in particular for providing electric energy from a solar panel to an electric network, comprising: an input section (10) for receiving a substantially direct voltage; an H-bridge (20) adapted to receive said substantially direct current through said input section (10) and designed to output a substantially alternating voltage, said H-bridge (20) being drivable at least in the following conditions: at least one operating condition, at which electric energy is supplied to said electric network (2); a first and a second recirculation condition, at which a current flows through at least part of said H-bridge (20), and no electric energy is supplied to said electric network (2). The converter (1) further comprises: an output section (40) to supply said substantially alternating current to said electric network (2); an uncoupling module (50) operatively interposed between said input section (10) and said H-bridge (20) and configured for uncoupling said input section (10) from said H-bridge (20) at said first and second recirculation conditions of said H-bridge (20).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
