Abstract (en)
The invention presents a method, apparatus or kitchen hob (300) and a computer program product (370) to improve temperature control of a heat source (310, ..., 330), taking heat inertia of the heat source and a total thermal system of masses associated to a heating process in e.g. a kitchen hob into account. The invention takes care of the heat inertia present in the heat source and a total thermal system of masses associated to a heating process and correspondingly provides a transition phase (255) between a higher temperature level and a lower temperature level, wherein the power supplied to the heat source is controlled differently. In particular, in pulse-width control sub-phases with ascending power phases over time are provided after e.g. preferably a break when transiting from a higher power level to a lower power level. In this manner, temperature overshooting can be avoided, energy can be saved and a consumer using a kitchen hob does not have to frequently adjust the power level, because this is automatically effected according to the present invention.
