摘要： A dual coil induction cooking system and method for heating ferrous and non-ferrous cooking vessels. The system includes a first resonant circuit for inducing a current in a ferrous metal cooking vessel at a first frequency and a second resonant circuit, wired in a parallel combination with the first resonant circuit, for inducing a current in a non-ferrous metal cooking vessel at a second frequency. The system also includes a power source for powering the parallel combination, so that one of the first and the second resonant circuits is coupled to supply power through the parallel combination to a respective one of the cooking vessels. A method for coupling power to a load includes sweeping a parallel combination of resonant circuits with a variable frequency power, detecting a resonant frequency response corresponding to a metallic composition of the load, and simultaneously powering the parallel combination of resonant circuits at a frequency corresponding to the detected resonant frequency.

摘要： We form welded reinforced composites by heating a susceptor along the bond line with a time-varying magnetic field produced with a moving induction coil. To obtain more uniform heating across the susceptor when welding composite parts using induction heating, edge regions of lower absolute impedance or a lower longitudinal impedance than the transverse impedance counterbalance the higher current density and current that occurs near the edges. The susceptor has lower impedance at the edges by altering the aspect ratio (length/width) of openings in the susceptor, by folding the susceptor over onto itself, or both. Uniform heating is important to obtaining a uniform, consistent weld on which aerospace designers can rely.
摘要翻译： 我们通过使用移动的感应线圈产生的随时间变化的磁场沿接合线加热基座来形成焊接的增强复合材料。 当使用感应加热焊接复合材料部件时，为了获得更多的均匀加热，在绝缘阻抗较低的边缘区域或比横向阻抗平衡的较低纵向阻抗的边缘区域，边缘附近出现较高的电流密度和电流。 通过改变基座上的开口的长宽比（长度/宽度），通过将基座折叠到其本身上或两者上，基座在边缘具有较低的阻抗。 均匀加热对于获得航空航天设计师可以依靠的均匀，一致的焊接来说是重要的。

摘要： This relates to the heating of thick slabs for rolling and like purposes wherein there is a complete penetration of the slab by induced electrical energy wherein the starting current frequency is very low and wherein a maximum heating is obtained by increasing the current frequency to control through penetration of the induced current in the slab as the temperature of the slab rises and thus the restivity of the metal of the slab increases. Several heating systems are envisioned. These include a heating system of a length corresponding to the length of the slab and wherein the slab is stationary during the heating to the desired temperature, after which the slab is moved out of the heating apparatus. The second arrangement is similar to the first, but wherein a lower coil arrangement moves relative to the upper coil arrangement so as to remove and expose a heated slab. In these two systems, the frequency is progressively increased. In a third system, the heating system is relatively short and the slab being heated is moved therethrough. In this arrangement, there are a plurality of coil sets each having a current supply of a different and gradually increasing frequency.
摘要翻译： 这涉及用于轧制和类似目的的厚板坯的加热，其中通过感应电能完全穿透板坯，其中起动电流频率非常低，并且其中通过增加当前频率以通过穿透来控制最大加热 的板坯中的感应电流随着板坯温度的升高而升高，从而使板坯金属的复原性增加。 设想了几个加热系统。 这些包括长度对应于板坯长度的加热系统，并且其中板坯在加热到期望温度期间是静止的，之后将板坯移出加热装置。 第二布置类似于第一布置，但是下部线圈布置相对于上部线圈布置移动，以便移除和暴露加热的板。 在这两个系统中，频率逐渐增加。 在第三系统中，加热系统相对较短，被加热的板坯通过其移动。 在这种布置中，存在多个线圈组，每个线圈组具有不同且逐渐增加的频率的电流源。

摘要： A low-frequency electromagnetic induction heater includes a plurality of leg iron cores, a corresponding yoke iron core arranged on the leg iron cores, an induction coil wound around each leg iron core, and an iron plate or metal vessel for producing Joule heat with which the leg iron cores or induction coils are substantially in direct contact. The spaces between the yoke iron core, the leg iron cores and the induction coils are solidly filled with a resinous substrate which has been molded using molten resin. The induction heater produces less noise than other such heaters while providing a higher level of electromagnetic flux density.

摘要： An induction-heating apparatus includes at least two heating coils configured to heat an object to be heated by induction heating, at least two inverter devices connected to the at least two heating coils, respectively, and configured to supply power to the at least two heating coils, respectively, and a controller configured to control the at least two inverter devices. The controller compares driving frequencies, which are frequencies of the power supplied to the at least two heating coils, with each other, and change a driving frequency of a high-frequency coil having a higher driving frequency to a driving frequency of a low-frequency coil having a lower driving frequency. The controller controls an inverter device corresponding to the low-frequency coil in a first control state, and control an inverter device corresponding to the high-frequency coil in a second control state, which is different from the first control state.
