1. A power delivery system comprising:
a first current limiter and a second current limiter in parallel with each other, wherein a direct current (DC) voltage is provided to each of the first current limiter and the second current limiter;
a first transformer electrically coupled to the first current limiter, the first transformer associated with a first return current path;
a second transformer electrically coupled to the second current limiter, the second transformer associated with a second return current path, the second return current path being different from the first current path;
first differential signal traces electrically coupled to the first transformer; and
second differential signal traces electrically coupled to the second transformer, wherein the DC voltage is transmitted from the first transformer to the first differential signal traces simultaneous with the DC voltage being transmitted to the second differential signal traces by the second transformer.
