Abstract

Un generador de ondas del tipo con neutralización de los armónicos para sintetizar una onda senoidal reversible de frecuencia fundamente fo a partir de una pluralidad de ondas rectangulares, del tipo que incluye medios estáticos para generar una secuencia de N señales sucesivas que definen dos transiciones separadas entre sí por un ángulo eléctrico predeterminado, estando dichas señales a pi/N unas de otras, un sistema inversor de N etapas controlado por dichas transiciones para generar N impulsos de forma rectangular, respectivamente, N transformadores que tienen N arrollamientos primarios alimentados por dicho sistema inversor y que tienen medios de múltiples arrollamientos secundarios combinados para recibir dichas N tensiones de forma rectangular para sintetizar dicha onda senoidal, comprendiendo el generador de ondas: medios operativos con dichos medios estáticos en un instante deseado de inversión para invertir la secuencia de dichos impulsos de forma rectangular medios operativos condichos medios estáticos en dicho instante de inversión para invertir la polaridad de dichos impulsos de forma rectangular, medios operativos con dichos medios estáticos para iniciar la aparición de un primero subsiguiente a unos de dichos impulsos de forma rectangular en un ángulo de fase eléctrico por delante de dicho instante de inversión, siendo dicho ángulo de fase eléctrico igual al ángulo eléctrico que implica el último que precede a uno de dichos impulsos de forma rectangular que ocurren antes de dicho instante de inversión.
