Abstract: A method for controlling at least two three-phase power converters with asynchronous pulse-width modulation. The method further comprises the following steps: for each phase of each converter, the characteristics of the signals used to generate the modulating signal and carrier signal of each control signal of each phase of each converter are determined, for each converter, a phase shift is inserted between the carrier signals used to generate the phase control signals of the converter, for each phase, a phase shift is inserted between the carrier signals used to generate the control signals of the converters, for each phase of each converter, a pulse-width modulation control signal by intersection is determined resulting from the intersection of a modulating signal and a carrier signal, and the control signals are transmitted to the converters.
