Abstract
A step-down optical AC/DC transformer may include (1) an array of light-emitting devices that are disposed to be electrically coupled to an alternating current (AC) power source are connected in series with one another and (2) an array of photovoltaic cells that are optically coupled to the array of light-emitting devices and produce a direct current (DC) electrical output. Various other apparatuses, systems, and methods are also disclosed.
