<p>The invention relates to a system (4) for supplying an AC load (3) from a plurality of DC voltage sources (1, 2), comprising: - a first inverter (11) comprising: two input terminals for a first DC voltage source; two switches (111, 112) connected in series between the two input terminals; an output connected to a connection node between said switches of the first inverter; - a second inverter (21) comprising: two input terminals for a second DC voltage source; switches (211, 212) connected in series between the two input terminals; an output connected to a connection node between said switches of the second inverter, having the same potential as the output of the first inverter; - a control circuit (7) controlling the switches of the inverters (11, 12) by pulse width modulation, such that the inverters provide an alternating power supply at said outputs during a single half-cycle of the AC voltage to be generated.</p> |
