Abstract
The present invention relates to a method for controlling a cooking zone () of an induction cooking hob, wherein said cooking zone () comprises at least one induction coil () and is supplied by a generator () including a power switch. The method is performed by controlling the power switch by a gate driving signal () including a deactivation pulse length (Toff) and an activation pulse length (Ton). A switching period (T) of the gate driving signal () is given by the sum of the activation pulse length (Ton) and deactivation pulse length (Toff). A driving frequency (f) of the power switch is the reciprocal value of said switching period (T). The deactivation pulse length (Toff) depends on the resistance () and the inductance () of the induction coil (). The activation pulse length (Ton) is varied according to a requested power for the cooking zone (). A series of constant activation pulse length (Ton) is activated in order to determine the optimal deactivation pulse length (Toff).
