An electric conversion system (1) comprises an electric converter (2), with three phase modules (22), each connected to two input nodes (211, 212) in direct current, and to a single, respective output node (213) in three-phase alternating current. Each phase module (22) comprises controllable switches (23) and a flying capacitor (223). A control system (3) sends logical control signals to the switches (23), generated for the phase modules (22) as a function of three phase modulating signals (V<m>). The phase modulating signals (V<m>) are generated using a DPWM technique, adding, to three sinusoidal phase signals (V<sin>), a homopolar signal, generated so that, in different intervals, a phase modulating signal (V<m>) is saturated at a higher or lower end value. In each interval, the modulating signal to be saturated (V<f>) is selected in such a way as to minimize a combination of the circulating currents (I<223>) in the flying capacitors (223) of the three phase modules (22).
