Abstract
According to one embodiment, a method for converting alternating current voltage signals to Ethernet in-line power includes converting an alternating current voltage signal to an approximate direct current voltage signal, adding at least one odd harmonic of the approximate direct current voltage signal to produce a compensated direct current voltage signal, and conditioning the compensated direct current voltage signal to produce an Ethernet in-line power signal.
