Abstract

Un dispositivo de alimentación regulada, especialmente de un circuito de barrido de líneas de receptor de televisión, cuya etapa de salida lleva un primer interruptor electrónico de tipo bidireccional, accionado periódicamente para ser cerrado durante la ida del barrido, y abierto durante el retorno de éste conectado en paralelo a un primer montaje en serie, compuesto por bobinas de desviación de línea y por un primer condensador, denominado de ida, alimentando estas bobinas, durante el cierre del primer interruptor, con un segundo condensador, denominado de retorno, que forma un circuito resonante paralelo con la inductancia principalmente de las bobinas, durante la apertura del primer interruptor, y a un segundo montaje en serie, compuesto por un primer devanado de un transformador, denominado de línea, y por un tercer condensador, denominado de alimentación, que alimenta al primer devanado en tensión continua durante el cierre del primer interruptor.
