@article { , title = {A hybrid control method to suppress the three time fundamental frequency neutral-point voltage fluctuation in a VIENNA rectifier}, abstract = {This paper presents a solution to the control of the three times fundamental frequency fluctuation of the neutral-point in a VIENNA rectifier. A hybrid method combining a dynamic adjustment factor with a voltage deviation control of the split DC-link is proposed. The fluctuation of the neutral-point has been analyzed and the reason for the three times fundamental frequency fluctuation has been described using a mathematic model. As well as minimizing the three times fundamental frequency component in the neutral-point voltage the proposed control method also provides immunity to the influence of changes in the capacitor voltage. Furthermore, significant fluctuation in the neutral-point voltage caused by asymmetric capacitor parameters or unbalanced load can be effectively reduced by using a hybrid control method combining additional adjustment coefficients. The feasibility and effectiveness of the proposed strategy has been verified through the presented simulation and experimental results.}, doi = {10.1109/JESTPE.2015.2503125}, eissn = {2168-6785}, issue = {2}, journal = {IEEE Journal of Emerging and Selected Topics in Power Electronics}, publicationstatus = {Published}, publisher = {Institute of Electrical and Electronics Engineers}, url = {https://nottingham-repository.worktribe.com/output/765665}, volume = {4}, keyword = {Capacitors, Fluctuations, Rectifiers, Mathematical model, Voltage control, Harmonic analysis, Switches}, year = {2015}, author = {Song, Wei-Zhang and Xing, Fei-Xiong and Yang, Hua and Empringham, Lee and De Lillo, Liliana and Wheeler, Patrick and Li, Jie and Zhong, Yan-Ru} }
