摘要： Certain aspects involve a powered shelf system that can inductively provide power to electrical components of consumer product packages. The powered shelf system can include a housing, a primary inductor, a controller, and a pusher system. The primary inductor can be coupled to or included in the housing. The controller can apply an electrical current to the primary inductor in accordance with a maximum power requirement for the powered shelf system. The applied electrical current can be sufficient to create a magnetic field from the primary inductor that has a minimum field strength at a specified distance from the primary inductor. The minimum field strength can be sufficient to induce a minimum current in a secondary inductor for powering an emitting device that is electrically coupled to the secondary inductor. The pusher system can position the secondary inductor at the distance from the primary inductor.
