wherein the control unit (15) is configured:
to sense an electric parameter regarding the first induction heater (3) in a first resonant circuit (65), preferably a current through the first induction heater (3) or a voltage in a point of the first resonant circuit (65), when the first induction heater (3) is not fed from the switching converter (16) and a first auxiliary switch (30) closes the first resonant circuit (65) in such a way that the at least resonant capacitor assembly (60; 62) is connected to the first induction heater (3) by means of the first auxiliary switch (30) and a damped oscillation occurs between them;
to sense an electric parameter regarding the second induction heater (4) in a second resonant circuit (65), preferably a current through the second induction heater (4) or a voltage in a point of the second resonant circuit (65), when the second induction heater (4) is not fed from the switching converter (16) and the second auxiliary switch (40) closes the second resonant circuit (66) in such a way that the at least resonant capacitor assembly (61; 62) is connected to the second induction heater (4) by means of the second auxiliary switch (40) and a damped oscillation occurs between them;
