1. A method of distributing power from an input source to a load, where the load may vary over a normal operating range, comprising:

  • using a first regulator at a first location to convert power from the input source at a source voltage, Vsource, and deliver a controlled DC voltage, Vf, to a factorized bus;

    using the factorized bus to carry power from the first regulator to a remote location separated by a distance from the first location;

    using a voltage transformation module (“

    VTM”

    ) at the remote location to convert power, via a transformer, from the factorized bus at an input voltage Vin, essentially equal to the voltage delivered to the bus, Vf, to a DC output voltage, Vout; and

    using in the VTM an essentially constant voltage gain, K=Vout/Vin, at a load current;

    wherein the VTM has an output resistance, Rout; and

    wherein the load is supplied with a voltage, Vload, essentially equal to the output voltage of the VTM, Vout, which is regulated by the first regulator using the factorized bus.
