@article { , title = {A Simple Current Control Strategy for a Four-Leg Indirect Matrix Converter}, abstract = {In this paper the experimental validation of a predictive current control strategy for a four-leg indirect matrix converter is presented. The four-leg indirect matrix converter can supply energy to an unbalanced three-phase load whilst providing a path for the zero sequence load. The predictive current control technique is based on the optimal selection among the valid switching states of the converter by evaluating a cost function, resulting in a simple approach without the necessity for modulators. Furthermore, zero dc-link current commutation is achieved by synchronizing the state changes in the input stage with the application of a zero voltage space vector in the inverter stage. Simulation results are presented and the strategy is experimentally validated using a laboratory prototype.}, doi = {10.1109/tpel.2014.2321562}, eissn = {1941-0107}, issn = {0885-8993}, issue = {4}, journal = {IEEE Transactions on Power Electronics}, pages = {2275-2287}, publicationstatus = {Published}, publisher = {Institute of Electrical and Electronics Engineers}, url = {https://nottingham-repository.worktribe.com/output/729302}, volume = {30}, keyword = {AC-AC Conversion, Matrix Converter, Four Leg Converters, Current Control, Predictive Control, Modulation Schemes}, year = {2015}, author = {Garcia, Cristian and Rivera, Marco and Lopez, Miguel and Rodriguez, Jose and Pena, Ruben and Wheeler, Patrick and Espinoza, Jose} }
