Controle de tensão na carga para motor/gerador a relutância variável de três fases

Abstract

The subject of this work is to present a switched reluctance machine (SRM) driver capable to control the machine as a motor/generator, allowing the transition between the modes of operation while the machine is running. Six load voltage control strategies developed to be applied to a switched reluctance generator was performed, being that the strategies AV2, TBV, Hi and AMV was developed in this work. A SRM simulation able to represent the machine as a motor/generator was implemented and the results were presented. The load voltage strategies showed in this work was tested through simulations and the results indicate that the strategy called AV2 was the best one, providing a better utilization of the mechanical energy from the primary source. A prototype was assembled and the experimental results showed that the machine operating as a motor/generator operate properly and all the load voltage strategies developed to switched reluctance generator kept the voltage on the load near to the reference value confirming the functionality of the strategies.
