Abstract
The invention relates to a method for calibrating a power control loop of an induction hob (1), the induction hob (1) comprising a power stage (10) including at least one induction element (21), a measurement unit (12) and a control unit (11), the method comprising the steps of: —coupling the at least one induction element (21) with a reference load; —powering the power stage (10) at predefined working conditions by means of said control unit (11); —deriving a measurement value being indicative for the power transferred from the power stage (10) to the reference load by means of said measurement unit (12); —providing the measurement value to the control unit (11); —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 (12) based on the correction value when operating the induction hob (1).
