In an electric power supplying apparatus (1) using three single-phase inverter circuits to output three-phase AC voltages, the ratio of output energies from DC power sources constituting those single-phase inverter circuits is controlled. One or more single-phase inverter circuits (5a,5b,5c), which each comprise a DC power source (5a1,5b2,5c3) and a switching circuit (5a2,5b2,5c2), are series connected to configure a single-phase power source circuit, the zero-phase voltage component (Vo) of the three-phase AC voltages from which is adjusted. La présente invention concerne un appareil d'alimentation électrique (1) utilisant trois circuits inverseurs monophasés pour produire des tensions alternatives triphasées, qui contrôle le rapport des tensions générées à partir des sources d'alimentation CC desdits circuits. Trois circuits inverseurs monophasés (5a, 5b, 5c), qui comprennent chacun une source d'alimentation CC (5a1, 5b2, 5c3) et un circuit de commutation (5a2, 5b2, 5c2), sont connectés en série pour former un circuit d'alimentation monophasé, la composante de tension à phase nulle (Vo) des trois tensions alternatives triphasées étant réglée.
