Abstract: An electric power supply system, comprising: a main switching cell (6) comprising a first main branch (14) and a second main branch (16) each including a main switch (T1, T2), and an auxiliary switching cell (10) connected to the main switching cell (6) and comprising a first secondary branch (20) and a second secondary branch (22) on the one hand, each including a secondary switch (T3, T4) and a connection branch (24) for connecting the auxiliary switching cell (10) to the main switching cell (6) on the other hand, the connection branch (24) including a switching inductor (L1), the main switching cell (6) and the auxiliary switching cell (10) being connected, cascaded from each other. The auxiliary switching cell (10) comprises at least two switching capacitors (C1, C2) positioned parallel to one of the secondary switches (T3, T4) for one of them and parallel to one of the main switches (T1, T2) for the other one. An aircraft comprising at least such a power supply system.
