<p>Power converting apparatus that comprises a plurality of capacitors (C1, C2) disposed in series on the direct-voltage side, and an electronic power converter (1) for converting the direct voltage supplied by the capacitors (C1, C2) into at least one alternating-voltage signal by means of a determined modulation, the alternating-voltage signal comprising at least one phase represented by a voltage wave that comprises a plurality of voltage levels dependent on the number of capacitors (C1, C2) on the direct-voltage side, switching from one level to another by means of a sidewall (2) dependent on the modulation. The apparatus comprises a controller for modifying the current (i m ) at a connection mid-point (O) between every two capacitors (C1, C2) in accordance with the direction of the slope and the value of at least one output current of the apparatus.</p> |
