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

This work presents the use of multilevel inverters in a non-sinusoidal permanent magnet synchronous machine to reduce harmonic content currents. Due con- struction this machine, back electromotive force characteristic, which has as main consequence presence ripple electromagnetic torque produced by machine. Such oscillations decrease efficiency and can cause vibrations motor shaft, reducing its useful life. To mitigate this, uses with flying capacitors synthesize voltages 3, 5, 7 9 levels, order stator currents, consequently torque. Qualitative analyzes are presented through total distortion weighted inverter output voltages, comparing performance half-bridge 2 levels.
