  • Publication number: 20240213767
    Abstract: A photovoltaic system, a relay detection method, and a power supply system. When a fault, for example, sticking of the relay is detected, the controller stops sending a PWM driver gating signal to the inverter, and stops driving of a switch transistor in the inverter, and the inverter stops outputting power, and then determines whether a voltage difference between two ends of the relay is greater than a preset value, to determine whether the relay is faulty. The controller stops sending the PWM driver gating signal to the inverter only within a preset phase range of a voltage of the filter capacitor, to ensure that the voltage of the filter capacitor has a large value. Because the voltage of the filter capacitor is large, an alternating current grid-to-ground voltage is pulled up, to avoid detecting the fault as an alternating current grid-to-ground short circuit.

  • Patent number: 11693037
    Abstract: A method employs an unmanned aerial vehicle to carry an electromagnetic field measurement system to overcome environmental obstacles in measuring environmental electromagnetic field. The electromagnetic field measurement system senses the electromagnetic field of a spatial position in the environment to generate a sensing signal, then processes the sensing signal to remove the high-frequency electromagnetic interference generated by the operation of the unmanned aerial vehicle itself from the sensing signal, and converts the processed sensing signal into a digital signal. The digital signal is processed to extract at least one wave according to a fundamental frequency and a harmonic order, thereby removing the low-frequency electromagnetic interference from the digital signal. The extracted wave is employed in calculating an environmental electromagnetic field value of the spatial location.
