Patent ID: 7692121

Claim:
A method for temperature control of a heating element, which is heated inductively by an inductor, to which electric power (P) is supplied via a control circuit, comprising: activating the temperature control at a first point in time (t 1 ) (ΔT); determining at said first point in time (t 1 ) a reference value (F R ) depending on at least one electric variable (v o , i o , P, I) of the control circuit, said electric variable depending on the temperature (T) of the heating element; and ensuring that said temperature (T) of said heating element conforms to a predetermined temperature value at at least one later point in time (t 2 -t 7 ), said ensuring including determining at a later point in time (t 2 -t 7 ) a comparative value (F v ) depending on said electric variable (v o , i o , P, I), determining a deviation of said comparative value (F V ) from said reference value (F R ), and, in the event that said comparative value (F V ) deviates from said reference value (F R ), supplying power (P) to the inductor depending on said deviation.
