Enhanced DC-Link Capacitor Voltage Balancing Control of DC–AC Multilevel Multileg Converters
IEEE Transactions on Industrial Electronics, 2015This paper presents a capacitor voltage balancing control applicable to any multilevel dc-ac converter formed by a single set of series-connected capacitors implementing the dc link and semiconductor devices, such as the diode-clamped topology. The control is defined for any number of dc-link voltage levels and converter legs (for single-phase and ...

DC Conductor Rail with Distributed DC Link Capacitors
2021 IEEE Fourth International Conference on DC Microgrids (ICDCM), 2021DC conductor rails are an attractive choice for many conveyor systems as commonly used in car factories. Replacing the DC link capacitances of the moving conveyors and of the DC supply by capacitors distributed along the conductor rail in a DC grid system can reduce mass and size of moving conveyors.

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.

A study on the effect of DC-link decoupling capacitors
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017DC-link capacitors are usually utilized in voltage source converters to stabilize the DC-link voltage and suppress the transmission of current harmonics into the power grid. To guarantee the reliability of voltage source converters, in addition to select the DC-link capacitors with optimum capacitance, appropriate rated voltage and enough ripple ...

DC-link voltage stabilization for reduced dc-link capacitor inverter
2009 IEEE Energy Conversion Congress and Exposition, 2009In conventional motor drive systems using pulsewidth modulation (PWM) inverters, large electrolytic capacitors are used for stabilization of the dc-link voltage. Since the electrolytic capacitors are bulky and reduce reliability of the system due to short lifetime, there have been many efforts to eliminate or reduce the electrolytic capacitors in the ...
