  • Patent number: 11502657
    Abstract: A clock driver circuit, including: an input stage, a double-ended to single-ended conversion stage and a driver output stage connected in sequence. The input stage includes two mutually loaded differential amplifiers and a common mode negative feedback loop. The differential amplifiers are connected to a differential clock signal for amplification to generate a common mode voltage. The common mode feedback circuit is connected to an output end of the differential amplifiers to stabilize the output amplitude of the common mode voltage. The double-ended to single-ended conversion stage converts a differential sine clock signal output by the double-ended common mode voltage into a single-ended square wave clock signal. The driver output stage includes a multi-stage cascaded push-pull phase inverter to improve the drive capability of the square wave clock signal.

  • Publication number: 20220329070
    Abstract: A method and a system for switching from grid-connected to grid-disconnected, and a power conversion system are provided. The method includes determining whether a power grid is abnormal based on a power grid parameter obtained when a PCS is grid-connected and operates in a current source mode, turning off a switching cabinet if the power grid is abnormal, switching from a current source mode to a voltage source mode, sending a command to instruct a grid-connected/grid-disconnected switch to switch from a grid-connected loop to a grid-disconnected loop, controlling an output parameter to smoothly transit from an abnormal parameter value recorded when the power grid is abnormal to a rated parameter value, and supplying power to a load according to the rated parameter value. In this way, seamless switching from grid-connected to grid-disconnected can be achieved, thereby ensuring stability of power supply.

  • Patent number: 11461699
    Abstract: A method of location determination with a WiFi transceiver and an AI model includes jointly training, based on various losses: a feature extractor, a location classifier, and a domain classifier. The domain classifier may include a first domain classifier and a second domain classifier. The losses used for training tend to cause feature data from the feature extractor to cluster even if a physical object in an environment has moved after training is completed. Then, the location classifier is able to accurately estimate the position of, for example, a person in a room, even if a door or window has changed from open to close or close to open between the time of training and the time of estimating the person's position.
