  • Induction heating device, radioactive waste melting process device equipped with said induction heating device, and radioactive waste melting and solidification process device
    Patent number: 11570856
    Abstract: Provided is an induction heating device with which discharging can be easily avoided even when a large electric current is used. The induction heating device comprises a high-frequency power supply provided with a connection portion for an alternating-current power supply, and a heating coil portion connected to the high-frequency power supply. In the heating coil portion, a plurality of coils include n coils surrounding a cavity portion in a plane, wherein the plurality of coils are mutually connected in series via one of a plurality of capacitors.
