@article { , title = {Active DC voltage balancing PWM technique for high-power cascaded multilevel converters}, abstract = {In this paper a dedicated PWM technique specifically designed for single-phase (or four wire three-phase) multilevel Cascaded H-Bridge Converters is presented. The aim of the proposed technique is to minimize the DC-Link voltage unbalance, independently from the amplitude of the DC-Link voltage reference, and compensate the switching device voltage drops and on-state resistances. Such compensation can be used to achieve an increase in the waveform quality of the converter. This is particularly useful in high-power, low supply voltage applications where a low switching frequency is used. The DC-Link voltage balancing capability of the method removes the requirement for additional control loops to actively balance the DC-Link voltage on each H-Bridge, simplifying the control structure. The proposed modulation technique has been validated through the use of simulation and extensive experimental testing to confirm its effectiveness.}, doi = {10.1109/TIE.2014.2308139}, eissn = {1557-9948}, issn = {0278-0046}, issue = {11}, journal = {IEEE Transactions on Industrial Electronics}, publicationstatus = {Published}, publisher = {Institute of Electrical and Electronics Engineers}, url = {https://nottingham-repository.worktribe.com/output/722875}, volume = {61}, keyword = {Multilevel converters, Predictive control, Smart grid}, year = {2014}, author = {Tarisciotti, Luca and Zanchetta, Pericle and Watson, Alan James and Bifaretti, Stefano and Clare, Jon C. and Wheeler, Patrick} }
