Study on the effect of the voltage upon the electrolytic capacitors mounted in reverse polarity

This paper presents an experimental study on the effect of the voltage on the electrolytic capacitors mounted in reverse polarity. The experiments indicate that if the capacitors are charged with a constant current, the voltage across them tends to slowly oscillate due to the fact that the leakage current becomes very high instead of being closely to 0. The study is performed on 3 types of electrolytic capacitors from NCC: 4700 μF, 3200 μF and 2200 μF. All of the 3 types of capacitors are indicating a similar behavior.
