Abstract
UNA FUENTE DE ALIMENTACION PARA UN ELECTRODO DE UN TUBO DE RAYOS CATODICOS. PARA GENERAR UNA TENSION CATODICA (12) DEL TUBO (10) DE RAYOS CATODICOS QUE PROPORCIONA COMPENSACION DE NIVEL DEL NEGRO, UN DEVANADO SECUNDARIO (31) DE UN TRANSFORMADOR (11) DE RETORNO ESTA ACOPLADO EN SERIE CON UNA RESISTENCIA (R), UN CONDENSADOR (C1) Y UN DIODO RECTIFI CADOR (D3). DURANTE EL RETORNO DEL HAZ ELECTRONICO, UN IMPULSO DE TENSION (VSIC SC) ES GENERADO ENTRE TERMINALES DEL CONDENSADOR CON UNA MAGNITUD QUE AUMENTA CUANDO AUMENTA EL VALOR MEDIO DE LA CORRIENTE DE HAZ (ISIBEAM SC). EL IMPULSO DE TENSION HACE QUE LA TENSION CATODICA (+VSI1 SC) DISMINUYA PRIMERO CUANDO AUMENTA LA CORRIENTE DE HAZ.
