Item Implementation of an electrical micro-grid through matrix converters connected in parallel(2010) Planas, Estefanía; Ibarra, Edorta; Ormaetxea, Enekoitz; Andreu, Jon; Gabiolay, Igor; POWER ELECTRONICS AND SYSTEM EQUIPMENTThe matrix converter (MC) arouses a growing interest because it provides many advantages. On the other hand, the association of these converters in parallel makes the operation of the system operation more reliable and offers the possibility of creating electrical micro-grids. This article presents a parallel association of MCs by droop parallelization technique, which allows the control of several parallel MCs without needing communication between them. This configuration also offers the possibility to achieve an even load sharing. The obtained results demonstrate the feasibility of this technique.Item Innovative solutions in power electronics for variable speed wind turbines(2006) Villate, J. L.; Robles, E.; Ibáñez, P.; Gabiola, I.; Ceballos, S.; GENERAL; RENOVABLES OFFSHORE; SG; POWER ELECTRONICS AND SYSTEM EQUIPMENTWind energy has experienced a dramatic development over the last decade. Offshore wind farms with multimegawatt machines and variable speed solutions are gaining ground. The power converter is a key component in modern wind turbines with higher power, higher efficiency and lower costs. In addition, the utilities demand increasingly exacting power quality requirements, which can only be met if research on power converters is done. This paper presents a survey of existing power electronics solutions for wind turbines, covering trends and new studies in this field.
