Abstract:
A reactor for linking a transformer to a rectifier, the transformer generating a multiphase AC output signal comprising a plurality of three phase signals, each of the three phase signals comprising a first, a second and a third output current of substantially similar magnitude, each of the first, second, and third output currents being spaced one hundred and twenty degrees apart, wherein the first, second, and third output currents of each of the three phase signals are offset from the first, second, and third output currents of another of the three phase signals by a predetermined angle, respectively, and the rectifier is for receiving and rectifying the multiphase AC output signals to provide positive and negative DC bus currents, the reactor comprising:first, second and third cores; and a plurality of winding subsets, the plurality of winding subsets being equal in number to the plurality of three phase signals, each winding subset including at least first, second and third windings linked to the first, second and third outputs of the corresponding three phase signal, the windings being arranged on the cores such that at least a winding segment from each of the plurality of winding subsets is wound about each of the first, second and third cores.
