Active DC-link capacitor harmonic current reduction in two-level back-to-back converter [PDF]

open access: yesIEEE Transactions on Power Electronics, 2015
The paper proposes a method of active switching harmonics current reduction in the DC-link capacitor of a two-level, three-phase, back-to-back converter. Based on the derived analytical solution for switching harmonic currents in the DC-link, it is shown

Analysis of the DC-Link Voltage Ripple for the Three-Phase Voltage Source Converter under Nonlinear Output Current

open access: yesEnergies, 2022
The dc-link voltage ripple plays an important role in dc capacitor design for three-phase voltage source converters (VSCs). However, the analytical models of the dc-link voltage ripple have rarely been reported for VSCs with nonlinear output current ...

Transient analysis of a unified power flow controller and its application to design of the DC-link capacitor [PDF]

open access: yes, 2001
This paper presents a transient analysis of a unified power flow controller (UPFC), and design of capacitance of the dc-link capacitor based on that analysis. Active power flowing out of the series device in transient states is theoretically discussed to

Health Monitoring of DC link Capacitors

open access: yesChemical Engineering Transactions, 2013
Electrolytic and metallized polypropylene film (MPPF) capacitors are among the most popular capacitors used in electronic equipments. The choice of capacitors is of major importance because one of the most frequent causes of the equipment breakdowns results from the failure of capacitors, and will therefore determine the overall lifetime of the system.

Full-bridge modular multilevel converter (FB-MMC) with extended control range [PDF]

open access: yes, 2015
This paper presents an attractive control scheme that decouples cell capacitor voltage regulation of the FB-MMC from the dc link voltage regulation. This is achieved by manipulating both ac and dc components of modulation functions.
