Abstract

UN CIRCUITO DE REFLEXION (100) GENERA EN EL CIRCUITO DE REFLEXION RESONANTE (78) UNA PRIMERA TENSION DE NO ALIMENTACION EN UNA FRECUENCIA HORIZONTAL. UN INTERRUPTOR, (Q2) GENERA EN UN SEGUNDO CIRCUITO RESONANTE (78) UNA SEGUNDA TENSION TENSION DE NO ALIMENTACION EN LA FRECUENCIA HORIZONTAL QUE TIENE UNA FASE RELATIVA QUE PUEDE CONTROLAR LA PRIMERA TENSION DE FALTA DE ALIMENTACION. LA PRIMERA Y SEGUNDA TENSION DE NO ALIMENTACION SE SUMAN Y APLICAN A UN TRIPLICADOR DE TENSION (101) QUE PRODUCE UNA TENSION RECTIFICADA. UN CIRCUITO DE CONTROL (103) VARIA LA FASE DEL SEGUNDO VOLTAJE DE NO ALIMENTACION (V3) DE FORMA NEGATIVA HACIA ATRAS QUE ESTABILIZA EL VOLTAJE ULTIMO (U) SOBRE UN RANGO DE VARIACION DE LA CORRIENTE DEL HAZ.
