Abstract (en)
The method involves providing an alternating supply voltage and a frequency converter with an adjustable switching unit. The operating frequency of the switching unit and/or the frequency converter is increased from a frequency base in the course of half cycle of the voltage. The frequency is then decreased to the base, so that the frequency amounts to the base, at the zero crossing of the supply voltage. An independent claim is also included for an arrangement for power supply of an induction heating device.
