  • INDUCTION HEATING SYSTEM, INDUCTION HEATING METHOD, OUTPUT MONITORING APPARATUS, OUTPUT MONITORING METHOD, AND INDUCTION HEATING APPARATUS
    Publication number: 20210368589
    Abstract: An induction heating system includes induction heating apparatuses, each including a high-frequency current transformer, a low-frequency current transformer and a heating coil, a high-frequency input switch connected to the high-frequency current transformer, a low-frequency input switch connected to the low-frequency current transformer, a first power source to output a high-frequency electric power and a low frequency electric power, a second power source, a first power source output switch connectable to the first power source, a second power source output switch connectable to the second power source, and a switch controller. Each induction heating apparatus includes a heater controller to send a signal to the switching controller to turn on one of the first power source output switch and the second power source output switch, to turn off the other, and to switch on or off each of the high-frequency input switch and the low-frequency input switch.
    Type: Application
