  • Patent number: 12273048
    Abstract: Embodiments of this application disclose an inverter apparatus and an inverter apparatus control method. The inverter apparatus includes an inverter circuit and a control unit, and the control unit detects a driving mode of the inverter circuit based on a running state of the inverter circuit. When the inverter circuit outputs reactive power and an output current amplitude is greater than a current threshold, the control unit controls the inverter circuit in a full-bridge two-level bipolar control mode; and in other cases, the control unit controls the inverter circuit in a three-level control mode. This reduces a risk of breaking down horizontal bridge semiconductor switching devices by a voltage spike in an active turn-off process.

  • Patent number: 12266211
    Abstract: In implementations of the subject matter as described herein, there is provided a method for forgery detection of a face image. Subsequent to inputting a face image, it is detected whether a blending boundary due to the blend of different images exists in the face image, and then a corresponding grayscale image is generated based on a result of the detection, where the generated grayscale image can reveal whether the input face image is formed by blending different images. If a visible boundary corresponding to the blending boundary exists in the generated grayscale image, it indicates that the face image is a forged image; on the contrary, if the visible boundary does not exist in the generated grayscale image, it indicates that the face image is a real image.

  • Patent number: 12249905
    Abstract: A serial-parallel converter protection system includes a controller, a drive, a first switching transistor, and a second switching transistor. An input terminal of a converter is connected to an output terminal of the converter through the first switching transistor. The output terminal of the converter is connected in parallel with the second switching transistor. When an output voltage of the converter is greater than a first threshold, the controller controls the first switching transistor to be turned off and controls the second switching transistor to be turned on. In some embodiments, when the output voltage of the converter is greater than the first threshold, the controller controls the first switching transistor to be turned off and controls the second switching transistor to be turned on, so that the converter is bypassed, thereby preventing a voltage and a current from impacting a component inside the converter.
