1. A power transfer system for transferring power from a power source having predefined voltage parameters or predefined current parameters to a load across which it is desirable to develop a predefined load voltage or through which it is desirable to develop a predefined load current, said power transfer system comprising:

  • input power-form converting means for receiving input power from the power source and for converting the received input power into an intermediate power form having an intermediate voltage and an intermediate current, where at least one of the intermediate voltage and the intermediate current exceeds a corresponding one of the predefined load voltage and predefined load current that are to be desirably produced at the load;

    intermediate power-form splitting means, coupled to the input power-form converting means, for splitting at least one of the intermediate voltage and the intermediate current in an essentially lossless manner into a first split part and a second split part, where the first split part substantially matches at least a corresponding one of the predefined load voltage and predefined load current that are to be desirably produced at the load and the second split part represents excess energy;

    transfer means, coupled to the intermediate power-form splitting means, for transferring the first split part to the load; and

    excess power storage means, coupled to the input power-form converting means, for storing the excess-representing second split part.
