Abstract

An output power regulating device for a radiant heating arrangement (2) having a temperature sensor (3) for detecting the temperature of the cooking surface (1), and a preselector (4), is to be so designed that it only supplies the required amount of energy to the radiant heating arrangement (2) in dependence on the thermal loading. For that purpose a microcontroller (10) cyclically detects the variation in respect of time of the actual temperature and the deviation thereof from the reference value. A memory (12) contains a value matrix for the possible pairs in respect of the variation and the deviation in the actual temperature. The microcontroller (10) takes the appropriate regulating value from the value matrix and with that value controls the radiant heating arrangement (2).
