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

Verification of frequency converter with small DC-link capacitor
2005 European Conference on Power Electronics and Applications, 2005Traditionally, large DC-link capacitors have been used in voltage source inverters. By using MPPF-type capacitor the line current harmonic content is improved and the unreliable electrolytic capacitor can be omitted. In this paper, the dynamic behavior of an inverter with small DC-link capacitor has been studied by simulations and laboratory tests.

This paper investigates universal start-up procedure for Flying Capacitor Converter (FLC). Main part of this procedure is pre-charging of the dc-link and flying capacitors. This method is usable for voltage pre-charging in rectifier as well as inverter mode of the multilevel FLC converter. This specific feature is based on use of converter topology and

In some applications, to increase the system power density and lower the system cost, the dc-link capacitance of PMSM drives needs to be reduced. However, such practice may cause considerable dc-link voltage fluctuation. In this study, a method is proposed to reduce the dc-link voltage fluctuation.

Optimization Tool for Dc-Link Capacitor Bank Design in PV Inverters
2019 10th International Conference on Power Electronics and ECCE Asia (ICPE 2019 - ECCE Asia), 2019The development of a tool is presented for optimizing dc-link capacitors design in PV inverters. Reliability of power converters is well known to be one of the bottlenecks for decreasing the cost of renewable energy systems. Thus, this paper proposes an analysis and design method for estimating the lifetime performance of multiple capacitor bank ...
