Three-phase inverter system, with harmonics neutralization of less than 11 and with regulation of the output voltage, characterized by having: an autonomous inverter with pulse width modulation, with controlled valves and with current return diodes, which has two three-phase outputs whose voltages are equal but 30 degrees out of phase; and whose valves are made conductive three times per period of the output voltage; two three-phase transformers respectively connected on each of the three-phase outputs of said corrugation whose coupling indices differ by 30 degrees so that their secondary voltages are in phase, whose transformation ratios are equal and whose secondary windings are joined in series to constitute the exit phases of said inverter system, with output neutral; a control logic of the inverter valves, on the one hand, allowing the phase-shifting of the 30-degree voltages, on the other hand regulating the amplitude of the output voltage of the system by regulating the modulation in width of the pulses of the signals applied to the valves sent from the inverter, so that they conduct three times per period of the output voltage.
