Abstract (en)
The invention relates to an induction heating unit (1), comprising at least one resonant tank (30) with at least one induction heating element (32, 33), a power requesting unit (60) for requesting a power (PR) of the at least one induction heating element (32), a driving unit (52) for driving the resonant tank (30), in particular by oscillating the resonant tank (30) by means of a switching element (35), by a driving signal comprising a series of subsequent sequences for generating a heating power (PH), each sequence comprising a first subsequence (S1) with a first alternating signal and with a first subsequence duration (D1), causing an activation of the resonant tank (30) with a predetermined power (PM), a subsequent second subsequence (S2) with an at least essentially non-alternating signal and with a second subsequence duration (D2), causing a deactivation of the resonant tank (30) and a subsequent third subsequence (S3) with a second alternating signal and a with a third subsequence duration (D3), causing an activation of the resonant tank (30) with less than the predetermined power (PM), an induction cooking device and a corresponding method.
