- Abstract
The failure of aluminum electrolytic capacitors is considered as one of major failure modes of the power supplies. The paper presents an electrolytic capacitor parameters monitoring circuit. The monitoring circuit allows to control basic electrolytic capacitor parameters such as capacity and ESR. An approach for detecting the possibility of a two-stage PFC&LLC topology power supply failure caused by the aging of the electrolytic capacitor without capacitance calculating is proposed.
