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

A method for controlling the provision of electric power to an induction coil of an induction cooking appliance, the induction cooking appliance comprising the induction coil and a circuitry that includes a first switching element configured to control a pulsed electric power to the induction coil, and a capacitor connected in parallel with the first switching element, the method comprising the steps of:

• receiving a rectified AC-voltage at an input of the circuitry, the rectified AC-voltage having a period that includes a first phase, and then a second phase, and then a third phase, wherein the period of the rectified AC-voltage is periodically repeated;
• performing a first circuit control step during the first phase of each of the periods of the rectified AC-voltage, wherein the first circuit control step comprises discharging the capacitor to reduce a voltage of the capacitor from an initial voltage value to a reduced voltage value, wherein said discharging is performed by a first switching operation, during which a discharging circuit and/or the first switching element is gradually changed from a closed state to an opened state;
• performing a second circuit control step during the second phase of each the periods of the rectified AC-voltage, wherein the second circuit control step comprises starting a second switching operation that comprises switching the first switching element;
• and
• performing a third circuit control step during the third phase of each of the periods of the rectified AC-voltage, wherein the third circuit control step includes stopping the second switching operation, such that the voltage of the capacitor is equal to a final voltage value at the end of the third phase.
