Claim of US Patent No. 10,716,173

1. Method for calibrating a power control loop of an induction hob, the induction hob comprising a power stage including at least one induction element, a measurement unit and a control unit, the method comprising the steps of:coupling the at least one induction element with a reference load by inductance formed therebetween;
powering the power stage at predefined working conditions by means of said control unit;
deriving a measurement value being indicative for power transferred from the power stage to the reference load by the inductance formed therebetween by means of said measurement unit;
providing the measurement value to the control unit;
calculating a correction value based on the measurement value and a reference value;
storing the correction value in a storage entity in order to modify measurement values provided by the measurement unit based on the correction value when operating the induction hob.
