1. An apparatus comprising:

  • an inductor that is adapted to magnetically coupled to power sourcing circuitry;

    a rectifier that is coupled to the inductor and that outputs a direct current (DC) signal;

    a protection circuit that is coupled to the rectifier and that is adapted to limit the DC signal; and

    a controller that is coupled to the protection circuit, that is adapted to output a system voltage and a system current to a load, and that is adapted to output a charging voltage and a charging current to a battery, wherein the controller adjusts the charging voltage and charging current so that the system voltage is maintained above a predetermined threshold.
