Abstract

Un transmisor de energía (101) comprende un accionador (201) que genera una señal de accionamiento para que una bobina transmisora genere una señal de transferencia de energía durante un intervalo de tiempo de transferencia de energía y una señal de prueba electromagnética durante un intervalo de tiempo de detección de objetos extraños. Un conjunto de bobinas de detección equilibradas (207, 209) comprende dos bobinas de detección dispuestas de tal manera que las señales inducidas en las dos bobinas de detección por un campo electromagnético generado por la bobina transmisora se compensan entre sí. Un detector de objetos extraños (205) se acopla a las bobinas de detección y realiza la detección de objetos extraños durante el intervalo de tiempo de detección de objetos extraños. El detector de objetos extraños (205) se dispone para detectar un objeto extraño en respuesta a un criterio de detección de objetos extraños que requiere que al menos una señal de un conjunto de bobinas de detección equilibradas (207, 209) exceda un primer umbral y que no sea mayor que un número umbral dado de al menos dos de las señales que exceden un segundo umbral.
