Abstract

EL CIRCUITO DE MEDIDA COMPORTA UN INTEGRADOR (10, R, C, 12) AL CUAL ESTA APLICADO UNA SEÑAL (V1) REPRESENTATIVA DE LA CORRIENTE QUE RECORRE EL ENRROLLAMIENTO PRIMARIO DEL TRANSFORMADOR DE SALIDA DE UN ONDULADOR. LA SEÑAL DE SALIDA (V2) DEL INTEGRADOR ESTA REBAJADA A CERO AL PRINCIPIO DE CADA PERIODO DE LA COMPONENTE ALTERNATIVA DE DICHA CORRIENTE Y ESTA APLICADA A UN CONTRASTADOR - BLOQUEADOR (14, 16, C2) EN EL CUAL LA SEÑAL DE SALIDA (V3) REPRESENTA LA SEÑAL DE SALIDA (V2) DEL INTEGRADOR JUSTO ANTES DE SU REBAJE A CERO. UN ESCALON INTERMEDIO (18, R2, R3, R4) ESTA DISPUESTO ENTRE EL INTEGRADOR Y EL CONTRASTADOR - BLOQUEADOR PARA REDUCIR LA INFLUENCIA DE LOS IMPACTOS DE CARGA LIMITANDO LA VERIACION MAXIMA POSIBLE DE LA SEÑAL DE SALIDA (V3) DURANTE EL PERIODO DE CONTRASTE.
