Abstract: A household appliance apparatus includes a first inverter, a second inverter, a first phase terminal designed for electrical connection to a first phase of a power supply network, a second phase terminal designed for electrical connection to a second phase of the power supply network, and a switching arrangement configured to assign each of the first and second inverters to each of the first and second phase terminals.

Abstract: An induction cooking appliance apparatus includes a power unit designed to supply an induction heating unit with power in one operating state, a power supply unit designed to supply energy to a further unit in the operating state, a main filter unit designed to filter the power unit, and a secondary filter unit designed to filter the power supply unit. The main filter unit and the secondary filter unit are designed at least in part as a single piece and share a common filter unit for filtering the power supply unit in an inactive mode of the power unit.

Abstract: Disclosed herein is metasurface modules configured to reduce the cost of integration of metasurface elements within a housing and methods of manufacturing thereof. One particular embodiment includes a metasurface module including: a secondary substrate; and a metasurface chip mounted on the secondary substrate. The secondary substrate laterally extends from all sides of the metasurface chip to completely surround the metasurface chip. The secondary substrate may be utilized to mount the metasurface chip within a housing which decreases the size of the metasurface chip and ultimately decreases manufacturing costs of the metasurface chip.

Abstract: An induction cooking appliance device includes an independent heating unit including an inductor, and a power supply unit configured to provide an alternating current for the first heating unit. The power supply unit includes a configuration unit configured to provide for a change of configuration of the power supply unit between a half-bridge topology and a full-bridge topology for supplying the first heating unit.

Abstract: Apparatus and methods are disclosed related to radio frequency (RF) power detection. One such apparatus includes a directional coupler, an RF switch, and an RF power detector. The RF switch can selectively change coupling between the directional coupler and the RF power detector. This can enable accurate power detection based on a ratio of power levels, without factory calibration or laser trimming.
