Abstract
Procedimiento para la generación de un sistema de tres tensiones alternas desfasadas, en cada caso en 120º el de amplitudes iguales y constantes a partir de dos tensiones continuas constantes y de igual magnitud, de polaridad opuesta, con utilización de conmutadores electrónicos, caracterizado por las siguientes etapas: a) generación de una primera tensión alterna de referencia de forma triangular, U{D,sub,1}, de amplitud constante con la magnitud de las tensiones continuas constantes, + U{sub,A}, - U{sub,A} y con una frecuencia controlada correspondientemente a la magnitud de una tensión continua, U{sub,E}, mediante cambio de carga de condensadores con los manantiales de corriente conmutados; b) generación de una tensión alterna de referencia adicional de forma triangular, U{Dsub,2} o U''{Dsub,2}, desfasada a elección en 120º el o -120º el frente a la primera tensión alterna de referencia, U{Dsub,1}, mediante suma algebraica.
