INDUCTION HEATING APPARATUS

摘要

An induction heating or cooking apparatus comprises an inductive heating coil (L), means (CT) for sensing the current IS of an a.c. supply applied to the heating coil (L), means (VR) for selecting the desired heat output of the apparatus, means (APC) for comparing the sensed current with an output of the selecting means (VR), and means (RL1) for varying the voltage of the supply to a heating coil (L) in accordance with the value of an error signal output from the comparing means (APC). Thus, the temperature which the base of a cooking utensil (P) stood on the coil (L) reaches is independent of the material of the utensil.
