Abstract

SE PRESENTA UN INVERSOR PARA LA ALIMENTACION DE UNA O MAS LAMPARAS DE DESCARGA (11;111A,111B) CON ELECTRODOS CALENTADOS (13,15), EL INVERSOR COMPRENDE UN CIRCUITO DE CARGA CON UN CIRCUITO RESONANTE EN SERIE (17,19,21,117A,117B;119;121) Y AL MENOS UNA LAMPARA(11,111A,111B), DOS CONMUTADORES CONTROLABLES (7,9;107,109) Y UN CIRCUITO DE CONTROL (25) PARA LOS MENCIONADOS CONMUTADORES QUE PROVOCA QUE DICHOS CONMUTADORES SEAN ALTERNATIVAMENTE CONDUCTORES. UN COMPONENTE DISIPATIVO NORMALMENTE AISLADO (33;133), QUE ESTA CONECTADO, CUANDO LA TENSION A TRAVES DEL CIRCUITO DE CARGA EXCEDE DE VALOR DADO, CON EL CIRCUITO DE CARGA, MODIFICA DE ESTA FORMA SUS CARACTERISTICAS PARA LIMITAR LA TENSION MAXIMA SIN VARIAR LA FRECUENCIA DE RESONANCIA DEL CIRCUITO DE CARGA.
