Description
Summary:This paper presents a hybrid AC-DC-AC converter topology applied to wind energy conversion systems. The converter is composed of a generator-side voltage source converter and a grid-side current source converter. By selecting the proper converter to either generator or grid-side, the system enhances the advantages of one converter while mitigates the disadvantages. In this way, this paper shows a study on the operational characteristics of the hybrid converter. The proposed converter has as main characteristics: short circuit protection, direct control for connection to the grid, boost-boost operation, low semiconductors losses and low total harmonic distortion. Results are presented in order to verify the operational characteristics of the converter and its feasibility of using, as well as perform comparison with the conventional back-to-back voltage and current source topologies. Simulation and experimental results are presented in order to validate the theoretical approach.
