Abstract
The space vector pulse width modulation (SVPWM) methods have been widely applied in the high-precision control of permanent magnet synchronous motors (PMSMs). This study investigates the high-frequency noise harmonic induced by SVPWM methods. The function model between the harmonic amplitude and switching frequency has been analytically established. Simulation and experimental results indicate that although the random SVPWM method disperses the sideband harmonic, the overall sound pressure level (SPL) of the PMSM remains high. Increasing the switching frequency can significantly reduce the sideband harmonic amplitude and acoustic noise. By applying the parallel power semiconductors into the voltage source inverter (VSI), the additional inverter loss induced by higher switching frequency can be reduced. This provides a theoretical reference for the selection of vector control methods and VSI topologies.
