Abstract:
An 2N+1-phase AC machine induction motor/generator arrangement, comprising:N AC machines, each of said N ac machines having 2N+1 windings through which alternating current flows;a controllable 2N+1-phase inverter for generating 2N+1 phases of current for driving said N machines;interconnection means coupled to said inverter and to said N AC machines, for interconnecting said N windings of said N AC machines so that the current flowing through each winding of each machine flows through windings of each of the others of said N AC machines; andcontrol means coupled to said inverter, for controlling said 2N+1 phases in N mutually orthogonal sets of phases, for thereby controlling said N AC machines independently of each other.
