Abstract: A method for dynamic wave form correction includes providing an input power signal by an AC power source and rectifying the input power signal by a frequency converter into a half waves signal whose half wave is delimited by two subsequent zero-crossings. The time lag between the two zero-crossings defines a half wave duration. The frequency converter converts the half waves signal into a working current signal for supplying an induction heating device. In a frequency shifting operation, the frequency of the working signal is first increased from a first base frequency to a maximum frequency, and is then decreased to a second base frequency different from the first base frequency within a time period smaller than the half wave duration. A zero crossing of the half wave signal is passed within the frequency shifting operation. An arrangement for dynamic wave form correction of a power supply is also provided.
