ABSTRACT:
There is disclosed a power supply for storing electrical energy in capacitors connected in series, the power supply having a function of shorting out capacitors at fault. Shorting means are connected in parallel with the capacitors, respectively. If any one of the capacitors is charged abnormally, it is detected by detection means. The terminals of this detected capacitor are shorted out by the corresponding one of the shorting means. The shorting means can also act as bypass means ancillary to parallel monitors, respectively. By detecting temperature rises of the bypass means, abnormal charging of the capacitors can be judged.
