This study intends to design an accelerated life test of the capacitor, a major component of the traction inverter in the KTX propulsion control system. Design of accelerated life tests is carried out according to the sequence of selection of failure mechanism, determination of accelerating stress and its range, determination of test conditions, determination and distribution of the number of samples. It is possible to estimate life at use temperature by using life-shortening effect of applied voltage and verify the life-shortening effect of applied voltage by performing accelerated life test. This accelerated life method can be applied to accelerated life tests of other products which are stressed by temperature and to which a certain voltage is irregularly applied.
