ABSTRACT:
An induction heating device for controlling the temperature distribution in an electrically conductive material, or susceptor, when heated by induced eddy currents in the material. A non-electrically conductive material can be heated in a controlled manner by placing the material near to the susceptor. Variable power is applied to multiple induction coil sections wound around the length of the susceptor from a power source by one or more switching circuits. The coil sections can be overlapped or counter-wound between adjacent coil sections, or provided power in a cascaded manner, to achieve desired temperature distributions in the susceptor. A control circuit is used to control the power applied to each coil section and the output of the power source. By placing a non-electrically conductive material near to the susceptor the material can be heated in a controlled manner.
