  • Patent number: 11804737
    Abstract: According to some embodiments, a wireless power transmitter is presented. In some embodiments, a wireless power transmitter includes a charging table; a plurality of movable transmitter coils incorporated into the charging table; and a control circuit coupled to sensors in the charging table and to the plurality of movable coils. In some embodiments, the control circuit is configured to detect a device placed on the charging table, determine a position of the device, move at least one of the plurality of movable transmitter coils to engage the device, communicate with the device to determine device characteristics, further configure the plurality of movable coils to engage with the device, and engage the device according to the device characteristics.

  • Patent number: 7586765
    Abstract: A switched current power converter includes an input power source, an output terminal, and a plurality of current stages. Each of the current stages includes a converter coupled to the input power source for providing a current and a switch circuit that selectively couples the current in such current stage to the output terminal. A control circuit decouples the input power source from the current stage converters upon detection of a low load condition. Optionally, the power converter includes a low load circuit responsive to the control circuit that selectively couples current to the output terminal during the low load condition.
