Abstract
This work aimed to develop a strategy for driving a three-phase induction machine using indirect field-oriented control and Space Vector pulse width modulation, aiming to control the speed and shaft currents in order to maintain a constant speed for variations in rotor load. Among the results obtained, it can highlight the slip of less than 1% after applying a load 50% higher than the nominal one supported by the machine. The SVPWM provided a maximum utilization of 104.58% of the converter’s DC bus in the overmodulation region and 100% in the linear region.
