Title (EN) INDUCTIVE HEATING EQUIPMENT
(FR) INSTALLATION DE CHAUFFAGE A INDUCTION
Abstract: front page image
(EN)In an inductive heating equipment based on a so-called inductive heating principle that magnetic material is heated by eddy current produced when the magnetic material intersects magnetic field of a heating coil (32), an inverter unit having a wide-range control on its output, in which zero-crossing of the voltage across the heating coil (32) is detected and a transistor (33) is controlled in a manner of pulse-width control in synchronization with the zero-cross detection output.
(FR)Dans une installation de chauffage par induction basee sur le principe de chauffage par induction ou le materiau magnetique est chauffe par des courants parasites produits lorsque le materiau magnetique intersecte un champ magnetique d"une bobine de chauffage (32), un inverseur ayant une commande a grande portee sur sa sortie, dans lequel le croisement zero de la tension sur la bobine de chauffage (32) est detecte et un transistor (33) est commande par largeur d"impulsions en synchronisation avec la sortie de detection de croisement zero.
