  • Patent number: 11921138
    Abstract: An insulation resistance detection device detects a voltage at a connection point between a coupling capacitor and a resistance in the case where a frequency signal is outputted to the resistance, and detects an insulation resistance between a ground portion and a power supply path based on a moving average value of a detection voltage. The insulation resistance detection device includes a first determination unit, a resistance detection unit, and a second determination unit. In response to a determination that the pulsation of the detection voltage is attenuated, the resistance detection unit detects the insulation resistance based on, instead of a first moving average value, a second moving average value calculated by using the detection voltage in a second range including a smaller number of detection voltages than in the first range.

  • Patent number: 11923756
    Abstract: A control apparatus for a power conversion apparatus acquires a detected voltage of an alternating-current power supply. The control apparatus determines a period from when the detected voltage exceeds a first determination value for determining a zero-up-crossing timing of an actual voltage of the alternating-current power supply until the detected voltage falls below a second determination value for determining a zero-down-crossing timing of the actual voltage to be a period during which the actual voltage has a positive polarity, and determines a period from when the detected voltage falls below the second determination value until the detected voltage exceeds the first determination value to be a period during which the actual voltage has a negative polarity. The first determination value is less than the detected voltage when the actual voltage is zero, and the second determination value is greater than the detected voltage when the actual voltage is zero.
