@article { , title = {DC-Link Capacitor Second Carrier Band Switching Harmonic Current Reduction in Two-Level Back-to-Back Converters}, abstract = {© 1986-2012 IEEE. This paper proposes an active switching harmonic current reduction method within the dc-link capacitor of two-level, three-phase, back-to-back converters. This method is based on the derived analytical solution for switching harmonic currents in the dc-link. It is shown that by controlling the pulse width modulation carrier waveform's phase angles, the harmonics in the second carrier band of the rectifier and the inverter can be synchronized such that cancellation occurs in the dc-link capacitor. This synchronization is provided by harmonic phase feedback control. The feasibility of the proposed approach has been verified experimentally and results are presented in this paper.}, doi = {10.1109/TPEL.2017.2706972}, eissn = {1941-0107}, issn = {0885-8993}, issue = {4}, journal = {IEEE Transactions on Power Electronics}, pages = {3567-3574}, publicationstatus = {Published}, publisher = {Institute of Electrical and Electronics Engineers}, url = {https://nottingham-repository.worktribe.com/output/861811}, volume = {33}, keyword = {converters, AC-DC power conversion, capacitors, harmonic analysis, switching functions, power quality, pulse-width modulation, testing}, year = {2018}, author = {Shen, Lei and Bozhko, Serhiy and Hill, Christopher Ian and Wheeler, Patrick} }
