Self-regulating heater employing reactive components.

摘要

Self-regulating electrical heating systems which comprise a constant voltage or constant current power supply and at least one heating unit which comprises a reactive component, a resistive heating component, and a temperatureresponsive component. Preferably the reactive component and the temperature-responsive component are combined in the form of a capacitor comprising a dielectric whose dielectric constant decrease with temperature or an inductor comprising a core whose permeability increases with temperature.
