DC-Link Capacitor Lifetime under Various Operating Conditions
2019 IEEE 13th International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG), 2019A grid-tied DC/AC converter transfers the energy to the power system under different operating conditions such as DC-Link voltage level, power factor, and instability in the grid voltage. There are some effects of the operating conditions to the DC-Link capacitor lifetime.

IECON 2021 – 47th Annual Conference of the IEEE Industrial Electronics Society, 2021
In order to avoid the failure of electrolytic capacitor due to the influence of ambient temperature, film capacitors are applied in the DC-link of permanent magnet synchronous motor (PMSM) drive systems. In this paper, an online estimation method of DC-link capacitance is proposed for the electrolytic capacitorless motor drive system. The power signals

Condition Monitoring of DC Link Electrolytic Capacitors in Adjustable Speed Drives
2007 IEEE Industry Applications Annual Meeting, 2007A new preventive maintenance strategy for the sensorless condition monitoring of inverter dc-link aluminum electrolytic capacitors based on equivalent series resistance (ESR) and capacitance C estimation is proposed. The main concept of the proposed method is to estimate the ESR and C of the capacitor, using the inverter whenever the motor is stopped ...

DC link capacitor selection for DC-DC converters
2020 12th Electrical Engineering Faculty Conference (BulEF), 2020This paper presents a strategy for DC-link capacitor selection for a low voltage DC-DC buck converter with load current in the range of 0.2kA up to 1kA. The power source is a rechargeable battery and despite its relatively low internal resistance, the choice of input capacitance is critical to the proper operation of the converter.

Method for balancing capacitors voltages on split DC-links
2016 18th European Conference on Power Electronics and Applications (EPE'16 ECCE Europe), 2016A technique to actively balance the voltages on series-connected capacitors designated to split DC sources whose loads comprise power converters is presented. It performs such balancing dynamically, enabling the voltage equalization even for small capacitors under wide power and voltages ranges. Proposal consists on lightly controlling the power of one

Investigation of performance of UPFC without DC link capacitor
Electric Power Systems Research, 2008This paper presents an analysis of the dynamic operation of unified power flow controller without DC link capacitor. In this scheme of UPFC the shunt converter present in the static synchronous compensator is operated as a current source rectifier, which maintains a fixed DC voltage and DC current on the DC link without capacitor.
