Method for controlling the provision of electric power to an induction coil

Abstract

The invention relates to a method for controlling the provision of electric power to an inductive element, in particular an induction coil (L), of an induction cooking appliance (), the induction cooking appliance () comprising a circuitry () with an input (), at least one switching element (S) for providing pulsed electric power to the inductive element, in particular the induction coil (L) and a capacitive element, in particular a capacitor (C) being connected in parallel, in particular in series, to the switching element (S), the method comprising the steps of: —receiving rectified AC-voltage (V) at the input () of the circuitry (); —discharging, in particular during a first section/phase (P), the capacitive element, in particular the capacitor (C) in order to reduce the voltage provided to the switching element (S), in particular during a first period of rectified AC-voltage (V); —after at least partially discharging the capacitive element, in particular the capacitor (C), starting, in particular as a second section/phase (P), a switching operation of the switching element (S), in particular during a second period of rectified AC-voltage (V); —stopping the switching operation after a switching operation time, in particular during the second period of rectified AC-voltage (V); —iterating the steps of discharging of capacitor (C), starting of switching operation and stopping of switching operation, in particular immediately subsequently, in subsequent periods of rectified AC-voltage (V).
