¿Qué quiere decir track cuando hablan de circuitos acoplados magnéticamente? Acá está el párrafo donde lo mencionan: "An ICPT system as shown in Fig. 1 comprises a power supplythat energizes an extended loop of wire (the primary winding ortrack) with a constant current at a frequency in the very low frequency range considerably above mains frequency and a pickup coil, or pickup coils, located along the track that couple power from the track by magnetic induction . These pickups may be moving or stationary. The wires in the track may be mounted on a monorail, be part of a skillet system, or buried under concrete or water." Gracias.
