1. An emergency battery converter system, comprising:

  • an emergency battery pack comprising;

    a storage device that stores power; and

    a step-up converter that converts a direct current (DC) output voltage of the storage device to a stepped-up DC output voltage that corresponds to a rectified voltage potential of a standard alternating current (AC) line voltage;

    a lighting driver that is adapted for an input of the standard AC line voltage, the lighting driver comprising;

    a rectifier circuit coupled to an output of the step-up converter to receive the stepped-up DC output voltage from the step-up converter as the input and responsively output a DC voltage;

    a step-down converter coupled to an output of the rectifier circuit, wherein the step-down converter converts the DC output voltage of the rectifier circuit to a stepped-down DC output voltage; and

    a regulator circuit coupled to the step-down converter to regulate the stepped-down DC output voltage to a regulated voltage; and

    an emergency luminaire that receives the regulated voltage.
