Estudo de aplicação de uma máquina de relutância variável e de um conversor para carros híbridos

Abstract

This work proposes the study of the application of a Switched Reluctance Machine (SRM) 8x6 with four phases in economy cars that have as operating principle the Internal Combustion Machine (ICM) four strokes with four cylinders with the purpose of improving the final performance of the car synchronizing the two machines with a half bridge converter. Bibliographical studies were carried out referring to the themes of SRM, ICM (with their respective position and phase sensors) and the half briedge converter. In light of this the coincidences between the characteristic functioning of the SRM in relation to that of the ICM were evaluated suggesting possible solutions for the synchronism taking advantage of the control signals of the ICM and proposals were made for the allocation of the SRM in the car. It can be concluded that the signals used in the control of the Otto cycle, in a 4-stroke engine of an IC, have profiles very similar to those applied to the control system of the firing of the coils in an SRM. If possible to generate this, this work will address initial and structuring concepts that contribute to future projects of development of the real synchronism between the SRM 8x6 and the ICM of a conventional economy vehicle (four strokes and four cylinders).
