Original Abstract Submitted

A capacitor deterioration detection device that detects deterioration of a filter capacitor which is provided in a filter connected to the AC side of a converter includes: a current measurement unit that measures current which flows in the filter capacitor; a calculation unit that uses the measurement value of the current which has been measured by the current measurement unit to calculate a parameter for determination of deterioration, and a determination unit that determines, on the basis of the result of a comparison between a reference value and the parameter for determination of deterioration which has been calculated by the calculation unit, whether or not the filter capacitor has deteriorated.
