摘要： A system for supplying AC driving voltages to a plurality of electric motors, wherein said plurality of electric motors comprise a main electric motor, one or more additional electric motors, and a variable voltage source associated with each phase of said main motor, wherein with each phase of each of said one or more additional electric motors a plurality of switches is associated, which are controllable for selectively acquiring a neutral switching state and at least one of a positive parallel switching state, and a positive serial switching state. The plurality of switches associated with a given phase of a given additional electric motor are switched to apply an effective voltage to said given phase corresponding to a set value of the corresponding phase voltage, and said variable voltage sources are controlled to provide a voltage corresponding to a voltage ensuring that an effective voltage corresponding the set value of the corresponding phase voltage of the main electric motor is applied to each of its phases, in consideration of the effective voltages applied to the phases of the additional electric motors by switching said plurality of switches associated with these phases.
