Abstract
The invention may enable provision of a method for facilitating operation of an induction heating device, and a pot detection method for an induction heating device and to an induction heating device. The induction heating device is characterized by determining a low point of a resonant cycle on a linking node of a parallel resonant circuit and a switching element, determining a low point voltage at the low point of the resonant cycle and switching on the switching element at the low point of the resonant cycle for a cycle duration that is determined depending on the low point voltage in such a manner that a low point voltage does not exceed a predetermined maximum value in the following resonant cycles.
