METHOD FOR CONTROLLING ASYNCHRONOUS IMPULSE WIDTH MODULATION OF AT LEAST TWO THREE PHASE POWER CONVERTERS.

摘要

A method of controlling asynchronous pulse width modulation of at least two three-phase power converters. The method comprises the following steps: for each phase of each converter, the characteristics of the signals entering into the generation of the modulating signal and the signal carrying each control signal of each phase of each converter are determined, for each converter, a phase shift between the carrier signals involved in the generation of the phase control signals of the converter is introduced, for each phase, a phase shift between the carrier signals entering the generation of the converter control signals, for each phase of each converter, determining a control signal in pulse width modulation by intersection resulting from the intersection of a modulating signal with a carrier signal, and transmitting the control signals to the converters.
