INDUCTION HOB

The invention relates to an induction-based cooking appliance comprising multiple heating power transferring elements (3a, 3b) and multiple heating power energy units (5a, 5b) for powering said heating power transferring elements (3a, 3b), each heating power energy unit (5a, 5b) comprising one or more power transistors for providing electrical power to the heating power transferring elements (3a, 3b), wherein:- said power transistors included in said multiple heating power energy units (5a, 5b) are wide bandgap transistors comprising semiconductor materials with a bandgap greater than 2eV configured to be operated in a first frequency range (FR1) and in a second frequency range (FR2) different to the first frequency range (FR1); or- a first heating power transferring element (3a) is powered by a heating power energy unit (5a) comprising a first type (T1) of power transistor adapted to be operated in a first frequency range (FR1) and a second heating power transferring element (3b) is powered by a heating power energy unit (5b) comprising a second type (T2) of power transistor adapted to be operated in a second frequency range (FR2) different to the first frequency range (FR1).
