  • Wireless Charging Control and Coordination
    Publication number: 20250055325
    Abstract: A first wireless power system having a first transmit device and a first receive device is operable in close proximity to a second wireless power system having a second transmit device and a second receive device. Each transmit device includes a respective coil driven by an inverter and measurement circuitry that controls the power transmitting devices to promote coexistence of the nearby systems.

  • N-color scalable LED driver
    Patent number: 10757775
    Abstract: Light-emitting diode (LED) driver systems that are scalable and can be used for N-color LED systems are provided. An LED system having N LED strings of different color can be efficiently driven with independently controllable constant current sources for each string from a single power source. The driver system can include a power converter having an inductor.
