1. A converter circuit for an n-phase inductive electrical load (n>

  • 1), comprising a first energy source and m first switch means (n>

    m≧

    1 and m/(n-m)≧

    2) each arranged to control the energization of a corresponding one of a first group of m phases of the load by the first energy source, the circuit further comprising a second energy source and n-m second switch means, the n-m switch means being arranged to control the energization of a corresponding one of a second group of n-m phases by the second energy source to transfer energy in its associated phase of the load to charge the first energy source.
