Abstract
The invention relates to a heating circuit for induction heating coils of an induction cooking hob and to an induction cooking hob including such a heating circuit. In the heating circuit, there are in each case two auxiliary half bridges interconnected to excite a respective resonant circuit for an induction heating coil such that the resonant circuit is excited by a full bridge. Thereby, lost heat is considerably reduced. Via a connecting device the auxiliary half bridges can be controlled to excite induction heating coils, which are partly or fully covered by a cooking vessel.
