Abstract
Heating systems and methods for inductive heating or a combination of resistive and inductive heating. A heater coil is inductively coupled to an article and a current signal is supplied to the heater coil. The heater coil generates a magnetic flux, based on the applied current signal, for inductively heating the article. Current pulses of a certain profile are used to enhance the rate, intensity and/or power of inductive heating delivered by the heating element or coil and/or to enhance the lifetime or reduce the cost of the inductive heating system.
