Conversor híbrido trifásico CA-CC-CA aplicado a sistemas de conversão de energia eólica.

Abstract

This work presents a hybrid AC-DC-AC converter topology applied in wind energy conversion systems. The topology is composed of a voltage source converter on the generator side and a current source converter on the grid side. The converters used operate in different ways, but, in general, they provide additional advantages to the system, canceling disadvantages that occur when using only one type of converter. In this way, this work shows a study on the conventional back-to-back voltage source and current source topologies and the study on the main characteristics, short-circuit protection, easy integration with the network, boost-boost and low operation. harmonic distortion rate. Results are presented in order to verify the operational characteristics of the converter and the feasibility of use, as well as to make a comparison with the conventional voltage source and current source topologies.
