Abstract

Esta solicitud describe una variedad de enfoques para generar señales sinusoidales de alto voltaje cuyo voltaje de salida puede ajustarse rápidamente, sin introducir artefactos de alta frecuencia en la salida. Cuando se usan estos enfoques, se pueden aplicar campos eléctricos más fuertes al tumor durante un mayor porcentaje de tiempo, lo que puede aumentar la eficacia de la terapia de TTFields. En algunas modalidades, esto se consigue impidiendo los ajustes de una fuente de alimentación de CC durante los momentos en que la salida de esa fuente de alimentación de CC está alimentando la señal de salida. En algunas modalidades, esto se logra sincronizando el funcionamiento de un generador de voltaje de CA y un interruptor electrónico que está conectado a la salida del generador de voltaje de CA.
