DC-AC converter, in particular for providing power supply from a solar panel to a mains power supply

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).
