Abstract: An abnormality detection method according to one aspect of the present disclosure is a method of detecting an abnormality in an AC signal to be input from an AC power supply. The method includes, where an ideal AC signal is represented as V0 sin ωt (V0: amplitude, co: angular frequency, t: time), calculating an arithmetic value including a value represented by sin2ωt+cos2ωt and determining that the AC signal is abnormal when the arithmetic value is out of a threshold range.
