  • Patent number: 11229092
    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.

  • Patent number: 10506748
    Abstract: A corona shielding system for an electric machine, for example a high-voltage machine, such as a generator, for generating electrical energy, an electric motor or else other electric operating means having a relatively high rated voltage, such as transformers, bushings, cables, etc, is disclosed. The corona shielding system may include a filler mixture including both planar and spherical particles. Therefore, the electrical conductivity, which is good in the presence of only planar particles in two spatial directions but is very poor in the third, can be adjusted anisotropically in a targeted manner.
