METHOD FOR CONTROLLING THE PROVISION OF ELECTRIC POWER TO AN INDUCTION COIL
摘要:
The invention relates to a method for controlling the provision of electric power to an induction coil (L) of an induction cooking appliance (1), the induction cooking appliance (1) comprising a circuitry (10) with an input (11), at least one switching element (S) for providing pulsed electric power to the induction coil (L) and a capacitor (C) being connected in parallel to the switching element (S), the method comprising the steps of:
- receiving rectified AC-voltage (V in ) at the input (11) of the circuitry (10);
- discharging the capacitor (C) in order to reduce the voltage provided to the switching element (S);
- after at least partially discharging the capacitor (C), starting a switching operation of the switching element (S);
- stopping the switching operation after a switching operation time; and
- iterating the steps of discharging of capacitor (C), starting of switching operation and stopping of switching operation in subsequent periods of rectified AC-voltage (V in ).
