Abstract
A control method implemented for an electric motor control installation, the control installation including a first converter having controlled switching arms for applying first voltage edges to a first electric motor connected to the first converter by first output phases, a second converter having controlled switching arms for applying second voltage edges to a second electric motor connected to the second converter by second outlet phases, the control method including a step of synchronizing first voltage edges with second voltage edges in order to minimize the common-mode currents generated by the installation.
