An AC electric rolling stock controller includes a comparator that compares an intermediate link voltage VEFC generated at a smoothing capacitor with a setting value A, a comparator that compares the intermediate link voltage VEFC with a setting value B less than the setting value A, and a delayer that delays an output of the comparator in a case in which the output of the comparator is significant. It is determined that the initial charging of the smoothing capacitor is complete in a case in which at least one of an output of the comparator and an output of the delayer is significant.
