Abstract

SISTEMA DE CALEFACCION DE ALTA FRECUENCIA QUE COMPRENDE UN CONVERTIDOR (33) CON UN INTERRUPTOR SEMICONDUCTOR (32), UN CONDENSADOR DE RESONANCIA (56), UN TRANSFORMADOR-ELEVADOR (35) PARA EL SUMINISTRO DE ENERGIA DE ALTO VOLTAJE Y ENERGIA DE CALENTAMIENTO A UN MAGNETRON (39), UN INDUCTOR (41) INSERTADO EN EL CIRCUITO DE CALENTAMIENTO DEL MAGNETRON (39) Y UNA UNIDAD DE CONTROL DEL CONVERTIDOR (34) PARA ACCIONAR EL INTERRUPTOR SEMICONDUCTOR. LA UNIDAD DE CONTROL DEL CONVERTIDOR (34) SE CONTROLA POR MEDIO DE UN SISTEMA DE ARRANQUE (42) AL INICIAR EL FUNCIONAMIENTO DEL CONVERTIDOR (33) PARA QUE EL TIEMPO EN EL QUE EL INTERRUPTOR SEMICONDUCTOR ESTE EN MODO DE CONDUCCION (32) SEA MAS CORTO QUE EL CORRESPONDIENTE A CONDICIONES NORMALES DE OPERACION Y EL TIEMPO EN MODO DE NO CONDUCCION SEA MAYOR QUE EL CORRESPONDIENTE DE CONDICIONES NORMALES DE OPERACION, CON EL FIN DE QUE EL PERIODO DEL INTERRUPTOR SEMICONDUCTOR SEA UN MULTIPLO DEL PERIODO DEL CIRCUITO DE RESONANCIA (35,36) FORMADO POR EL CONDENSADOR DE RESONANCIA (56), POR LO QUE LA FRECUENCIA DE OPERACION DEL CONVERTIDOR (33) EN EL MOMENTO DE ARRANQUE DEL MISMO ES PRACTICAMENTE IGUAL A LA FRECUENCIA DE OPERACION NORMAL.
