Abstract
A system supplies power from an AC voltage source to an electrical device. The system includes a plurality of AC/DC voltage converters having inputs connected to the AC voltage source and outputs connected to an electrical conductor. The system also includes a plurality of DC voltage converters, each having an input side connected to the electrical conductor and an output side connected to the electrical device. A converted DC or AC voltage is supplied to the electrical device. The system also includes a data coupling device coupled to the electrical conductor. The data coupling device allows communication with the electrical device via the electrical conductor using signals associated with a first frequency range while power is supplied to the electrical device via the electrical conductor. The system further includes clocking frequencies associated with one or more of the AC/DC converters being phase shifted with respect to each other to shift clocking noise from the first frequency range to a second frequency range and clocking frequencies associated with one or more of the DC voltage converters being phase shifted with respect to each other to shift clocking noise from the first frequency range to the second frequency range.
