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.

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.

Capacitance estimation of DC-link capacitor in brushless DC motor drive systems
2013 IEEE ECCE Asia Downunder, 2013This paper proposes a capacitance estimation method for the dc-link capacitor in brushless DC motor (BLDCM) drive systems. The proposed method is performed in the generating mode of the BLDCM. In this mode, the inverse dc current flows to the capacitor and the capacitor voltage is increased by the generating operation.
