Abstract

EL OBJETO DE LA INVENCION ES CREAR UN CIRCUITO SENCILLO QUE TRABAJE DINAMICAMENTE ESTABLE Y NO PRESENTE NINGUNA TENDENCIA A LA OSCILACION. UN MODULADOR PWM (12) CONTROLADO POR LA ALTA TENSION, ACCIONA UN INTERRUPTOR (15) QUE ESTA SITUADO ENTRE UNA TENSION DE OPERACION NEGATIVA (U2) Y LA BASE DEL TRANSISTOR DE ETAPA FINAL DE LINEAS (3) PUESTO A TIERRA MEDIANTE UN CONDENSADOR (11). EN PARTICULAR PARA RECEPTORES DE TELEVISION CON MUY ALTA TENSION DESDE 30 - 36 KV.
