Aplicação de Inversores Multiníveis para Redução do Conteúdo Harmônico das Correntes de uma Máquina PMSM N˜ao-Senoidal

Abstract: This work presents the use of multilevel inverters in a non-sinusoidal permanent magnet synchronous machine to reduce the harmonic content in the currents. Due to the construction of this machine, the back electromotive force presents a non-sinusoidal characteristic, which has as main consequence the presence of ripple in the electromagnetic torque produced by the machine. Such oscillations decrease the efficiency of the machine, and can cause vibrations in the motor shaft, reducing its useful life. To mitigat… Show more
