Abstract:
This abnormality detection method for a single-phase AC input voltage is executed by a control unit having a function of a phase locked loop, and includes: sequentially generating a simulated voltage waveform with a phase synchronized with the input voltage, by using the phase locked loop; and within a period until a next update of the generated simulated voltage waveform, comparing the instantaneous value of the input voltage with the simulated voltage waveform, and when the instantaneous value of the input voltage changes from a state of being along the simulated voltage waveform to a state of not being along the simulated voltage waveform, determining that the input voltage is abnormal.

Claim (Index 2):
The input-voltage-abnormality detection method according to  claim 1 , wherein\n when a difference voltage between the instantaneous value of the input voltage and the simulated voltage waveform is greater than a predetermined threshold value, the instantaneous value of the input voltage is determined to be in the state of not being along the simulated voltage waveform.
