摘要： An induction heating cooker includes a housing, an inner pot including a bottom part that includes a first area and a second area, and an inner pot storage part disposed in the housing. The inner pot storage stores the inner pot in a manner that the inner pot can be set or removed. Also, a first heating coil is below the inner pot storage part, arranged in a position facing the first area of the inner pot, that heats the inner pot by induction. Also, a second heating coil is below the inner pot storage part, arranged in a position facing the second area of the inner pot, that heats the inner pot by induction. A driving unit in the housing supplies high frequency currents to the first heating coil and the second heating coil, and a controller controls the driving unit.

摘要： An induction heating system includes a power inverter, an induction circuit, and a control circuit. The power inverter includes one or more transistors configured to receive a direct current (DC) input and produce an alternating current (AC) output. The induction circuit includes at least one working coil configured to receive the AC output and produce a first magnetic field, wherein the first magnetic field interacts with a ferrous material to generate heat in the ferrous material. The control circuit includes a processor and memory. The memory having instructions stored thereon that, when executed by the processor, cause the control circuit to receive an input, from a user, indicating a temperature set point, measure an inductance of the induction circuit, determine a resonant frequency of the induction circuit based on the inductance, and control the one or more transistors of the power inverter based on the resonant frequency and the temperature set point.

摘要： Systems and methods of pre-ageing of a metal strip during metal processing include passing the metal strip adjacent a magnetic rotor of a reheater. The systems and methods also include heating the metal strip through the magnetic rotor by rotating the magnetic rotor. Rotating the magnetic rotor induces a magnetic field into the metal strip such that the metal strip is heated.
