  • Device with a polyphase electrical machine, and related electrical machine
    Patent number: 8564238
    Abstract: The invention relates to a device having a polyphase electrical machine, wherein a plurality of inverters (36, 37, 38), which are controlled by an interlaced control modulated by pulse width to an identical cutoff frequency, provide, on the phase outputs thereof, an alternating voltage signal having an identical fundamental frequency, amplitude and phase to an electrical machine (2) that comprises at least two separate so-called star windings (33, 34, 35), each star winding being supplied by a related inverter, each phase output of which is connected to a phase circuit that includes the phase winding of the star winding, the device being characterized in that each phase circuit for a star winding has a negative mutual inductance with the homologous phase circuit of another star winding.
