Abstract

EN LOS APARATOS PREELECTRONICOS DE PRECONEXION, QUE CONSTAN DE ORIENTADORES DE CAMBIO, A LOS QUE SE ORIENTA LA TENSION DE CAMBIO DE LA RED, POR MEDIO DE LA CORRIENTE DE UN RECTIFICADOR, SE UTILIZA, AL MENOS UN CONDENSADOR CORRECTOR SINUSOIDE ADICIONAL.LAS CONEXIONES ADICIONALES DE ESTE TIPO MUESTRAN UNA ELEVADA DEPENDENCIA DE LA TENSION DEL CONDENSADOR DE CARGA, EN DEPENDENCIA DE LAS VARIACIONES DE LA TENSION DE CAMBIO DE LA RED Y/O DE LAS VARIACIONES DE LA CARGA DEL CIRCUITO DE CARGA, QUE TRAE CONSIGO INCONVENIENTES GRAVOSOS.SE PROPONE DISMINUIR ESTA DEPENDENCIA DE LA TENSION DEL CONDENSADOR DE CARGA DE LAS VARIACIONES DE TENSION DE CAMBIO DE LA RED, DE FORMA QUE SE CONECTEN EN PARALELO, EN LA ENTRADA DEL RECTIFICADOR DE CAMBIO, DOS DIODOS (DBL,DBH), EN SENTIDO CONTRARIO A LA TENSION DE CAMBIO. CUYO PUNTO DE ENLACE COMUN ES IGUAL PARA EL CIRCUITO DE SALIDA (LA) PARA EL CONDENSADOR ELECTRICO DE PUENTES (CH) ACTIVO Y ES EL CIERRE COMUN SITUADO EN LA SALIDA DEL RECTIFICADOR DE CAMBIO (WR).
