Abstract:
An induction hob including a first heating region with a first induction coil and a second heating region with a second induction coil is provided. First and second resonant converters drive an AC current through the first and second induction coils. The first and second resonant converters form a half-bridge resonant converter that is continuously driven such that a direction of current flow through the first induction coil and the second induction coil is alternating. The half-bridge resonant converter controls the output power of the first and second heating regions by varying the frequency of the AC current through the respective induction coil. The first and second resonant converters have different resonance frequencies such that the resonance frequency of the first resonant converter is at least 1.4 times higher than the resonance frequency of the second resonant converter.
