Abstract: Power systems and circuitry for generation of gradient magnetic fields in magnetic resonance imaging (MRI) systems are discussed herein. Embodiments may include the use of multiple gradient amplifiers that share a high-frequency power distribution unit, that may perform power distribution and power supply roles. The high-frequency power distribution unit may allow the use of a single power supply to drive multiple gradient amplifiers via a shared power bus. The gradient amplifiers may make use of modern semiconductor materials that provide high-frequency, high voltage performance, and may be implemented using single semiconductor bridges.

Abstract: This disclosure provides systems, methods and apparatuses for foreign object detection (FOD) in a wireless power transfer (WPT) system. An FOD protocol can be coordinated with different operating phases of the WPT system, such as an idle phase, a configuration phase, a connected phase, and a power transfer phase. An FOD assessment unit may perform foreign object detection assessments as part of each operating phase. The FOD protocol may include an initial idle phase foreign object detection assessment in the idle phase to handle a scenario in which a Power Receiver is placed on the Power Transmitter before the Power Transmitter has been turned on. The FOD assessment unit may adjust offset values used during each FOD assessment to improve accuracy of foreign object detection. The offset values may be adapted to accommodate movement of the Power Receiver after the initial idle phase foreign object detection assessment.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for a wireless power transmission apparatus that supports charging of one or more wireless power receiving apparatuses. The wireless power transmission apparatus may include multiple primary coils organized in groups (referred to as zones). Each zone may have a local controller for managing operation of one primary coil in the zone at a time. A master controller may selectively couple the primary coils to the local controllers. When a first primary coil is coupled to the local controller for a zone, the other primary coils in that zone may be disabled. The master controller may manage which primary coils from neighboring zones are coupled to their respective local controllers. Thus, when the first primary coil is activated, the adjacent primary coils (near the first primary coil) can be muted or disabled to mitigate undesirable interference.
