Abstract

SISTEMA DE CALENTAMIENTO POR INDUCCION. SISTEMA DE CALENTAMIENTO POR INDUCCION, QUE SE CARACTERIZA PORQUE LA ETAPA DE POTENCIA ESTA CONSTITUIDA POR UN SISTEMA RESOSANTE, BOBINA (4)-CONDENSADOR (5), CON DOS DISPOSITIVOS DE POTENCIA EN SERIE (7-7'') CON SU CORRESPONDIENTE RED DE EQUILIBRADO (9). ESTA TOPOLOGIA, CUYO CIRCUITO DE CONTROL HACE CONMUTAR LOS DISPOSITIVOS DE FORMA SUAVE, PERMITE ALCANZAR UNA MAYOR POTENCIA GLOBAL DEL SISTEMA. ESTE SISTEMA DE CONTROL SE CARACTERIZA TAMBIEN PORQUE CUENTA CON MEDIOS DE VARIACION DEL NIVEL DE POTENCIA A NIVELES ALTOS, Y DE VARIACION DE LA ENERGIA A NIVELES DE POTENCIA BAJOS, APLICANDO DURANTE INTERVALOS VARIABLES DE TIEMPO UNA POTENCIA FIJA. ASIMISMO, EL SISTEMA SE CARACTERIZA PORQUE LA DETECCION DE RECIPIENTES (6) SOBRE LA BOBINA (4) SE REALIZA A PARTIR DE UN COMPARADOR (18) QUE SENSA LA INTENSIDAD QUE CIRCULA POR UNA DE LAS REDES DE COMPENSACION, Y QUE ACTUA SOBRE EL SISTEMA DE CONTROL DESACTIVANDO EL SISTEMA EN UN MINIMO TIEMPO CUANDO NO EXISTA RECIPIENTE, O SEA INADECUADO.INDUCTION HEATING SYSTEM. INDUCTION HEATING SYSTEM, WHICH IS CHARACTERIZED BECAUSE THE POWER STAGE IS CONSISTED OF A RESOURCING SYSTEM, COIL (4) -CONDENSATOR (5), WITH TWO SERIAL POWER DEVICES (7-7 '') WITH ITS CORRESPONDING NETWORK OF BALANCED (9). THIS TOPOLOGY, WHOSE CONTROL CIRCUIT SWITCHES THE DEVICES IN A SMOOTH WAY, ALLOWS TO ACHIEVE GREATER GLOBAL POWER IN THE SYSTEM. THIS CONTROL SYSTEM IS ALSO CHARACTERIZED BECAUSE IT HAS MEANS OF VARIATION OF THE LEVEL OF POWER AT HIGH LEVELS, AND OF VARIATION OF ENERGY AT LOW POWER LEVELS, APPLYING DURING TIME VARIABLES A FIXED POWER. ALSO, THE SYSTEM IS CHARACTERIZED BECAUSE THE DETECTION OF CONTAINERS (6) ON THE COIL (4) IS CARRIED OUT FROM A COMPARATOR (18) THAT SENSES THE INTENSITY THAT CIRCULATES THROUGH ONE OF THE COMPENSATION NETWORKS, AND THAT WORKS ON THE SYSTEM OF CONTROL DEACTIVATING THE SYSTEM IN A MINIMUM TIME WHEN THERE IS NO CONTAINER, OR IT IS INADEQUATE.
