  • Publication number: 20230134335
    Abstract: In an embodiment, a power delivery system includes 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; a second transformer electrically coupled to the second current limiter; 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.

  • Patent number: 11546179
    Abstract: In an embodiment, an apparatus includes a source device including a first current limiter and a second current limiter in parallel with each other and a first transformer and a second transformer; a load device includes a third transformer and a fourth transformer in parallel with each other; and an Ethernet cable is electrically coupled between the source device and the load device, the Ethernet cable including first twisted pair lines and second twisted pair lines. A direct current (DC) voltage is provided to the first current limiter and the second current limiter, the first transformer is electrically coupled to an output of the first current limiter, and the second transformer is electrically coupled to an output of the second current limiter. The DC voltage is transmitted to the third transformer and the fourth transformer in parallel with each other via the first twisted pair lines and the second twisted pair lines.
