Resumo: |
The electric vehicle is increasingly present in our cities every day, and in the technological context it has shown great progress. Two essential elements to the success of these vehicles are the electric energy storage devices and electronic converters for processing and management of this energy. In this context, this dissertation presents a study on the current situation of the electric vehicle on the world scenario and its embedded technologies. Another object of research are supercapacitors for application in electric vehicles as an energy storage source and fast energy transfer. Thus, these studies provide the basis for achieving the main objective of this work: developing a bidirectional dc-dc converter for managing the energy flow provided by a supercapacitor module applied in an electric vehicle. A 2 kW laboratory a prototype with two phase interleaved dc-dc bidirectional topology has been implemented. Also, all used methodology is exposed, such as qualitative analysis, dimensioning of components, modeling and design of PI type controllers for the proposed converter. The digital implementation of the control circuit was designed using the dsPIC30f4011 by Microchip. Through simulation and experimental tests, it was evaluated the behavior of the converter and a performance comparison was held, with the converter showing efficiency above 90%. Thus, through theoretical and practical results it was possible to evaluate the performance of the converter and future studies involving the complete structure of a model of a small electric vehicle. |
