Abstract
An excitation system for heating food, water, or both in airplanes uses induction heating. The system includes at least one load circuit including an inductor that is excited with a load circuit AC voltage, a load circuit alternating current, or both the load circuit AC voltage and the load circuit alternating current. The load circuit AC voltage, the load circuit alternating current, or both the load circuit AC voltage and the load circuit alternating current are generated from an AC voltage signal that is amplitude-modulated with a frequency of a mains AC voltage from a voltage supply. The frequency of the AC voltage signal can be predetermined.
