  • Publication number: 20240230728
    Abstract: An abnormal detection circuit is provided. The abnormal detection circuit includes a conversion circuit, a voltage detection circuit, and a warning circuit. The conversion circuit receives a three-phase alternating current (AC) power and converts the three-phase AC power into a driving power. The voltage detection circuit detects each phase of the three-phase AC power. When a voltage value of at least one phase AC power of the three-phase AC power is abnormal, the voltage detection circuit uses the driving power to output at least one control signal corresponding to the abnormality. The warning circuit is driven by receiving the driving power and outputs at least one warning signal corresponding to the abnormality in response to the at least one control signal.

  • Publication number: 20240023229
    Abstract: An arrayed RF system includes an expandable mother circuit carrier and sub-modules implemented with RF packaged radiation structures. The sub-modules are embedded onto the mother circuit carrier through plug-in interfaces to form a replaceable and expandable co-structural structure. The mother circuit carrier receives and up-converts an input intermediate-frequency signal, thereby generating first high-frequency signals. The sub-modules are horizontally embedded on the mother circuit carrier, arranged into a one-dimensional or two-dimensional array, and electrically connected to the mother circuit carrier. The RF packaged radiation structures respectively receive first high-frequency signals, thereby emitting first RF signals. The RF packaged radiation structures receive second RF signals, thereby generating second high-frequency signals. The mother circuit carrier down-converts the second high-frequency signals, thereby generating an output intermediate-frequency signal.
