An apparatus provides multiple, phase-shifted power outputs, such as for driving a rectifier circuit of an electronic frequency converter. The apparatus connects to a multi-phase power source having a predetermined number of phases, such as a conventional three-phase alternating current source provided by a public utility. The apparatus causes a first phase shift in response to current flow from the power source through the input of the apparatus. The apparatus also includes an output. The output is responsive to current flow through the input such that the apparatus causes a second phase shift and provides multiple power outputs of different phases in response to the first and second phase shifts. The output of the apparatus includes at least two closed circuit winding groups. One closed circuit winding group is electrically phase shifted relative to another closed circuit winding group by the first phase shift, and each closed circuit winding group provides respective phase power outputs electrically phase shifted within itself by the second phase shift.
