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 una propiedad de una señal de las bobinas de detección que cumple con un criterio de detección de objetos extraños. Un transformador (1101) tiene un bobinado primario y un bobinado secundario acoplados en serie con el conjunto de bobinas de detección equilibradas. Un circuito de compensación (1103) se acopla al bobinado primario y se dispone para generar una señal de accionamiento de compensación para el bobinado primario que compensa un voltaje combinado del conjunto de bobinas de detección.
