    Patent number: 10602601
    Abstract: A creeping discharge element drive device of an embodiment includes a switching element, a current detector, a zero-cross detection circuit, a storage, and a controller. The current detector detects alternating currents flowing through the switching element. The zero-cross point detection circuit detects a zero-cross point of the alternating currents. The storage stores a first threshold value of a resonant period. The controller drives the switching element to apply a test voltage to the creeping discharge element, determines a resonant period of the alternating currents from the detected zero-cross points of the alternating currents, and restricts or stops the driving of the switching element in response to the resonant period exceeding the first threshold value.
