Abstract
The multi-level DC/AC converter, comprising: an input () connectable to a direct voltage source (), with a first connection () and a second connection () between which can be applied an input voltage (Vi); a half-bridge with a first controlled switch () and a second controlled switch () between which is positioned an output (U) of the converter; a first connecting branch () between the first controlled switch () and the first connection () and a second connecting branch () between the second controlled switch () and the second connection (); a third controlled switch () associated to the first controlled switch (), connectable in series to the first controlled switch to generate an output voltage exceeding a first limit value (Vi/2); a fourth controlled switch () associated to the second controlled switch (), connectable in series to said second controlled switch to generate an output voltage below a second limit value (−Vi/2).
