| 摘 要： | 为降低变频器供电引起的永磁同步电机(PMSM)电磁振动噪声,首先理论分析了变频器引入的PMSM振动噪声源,然后利用MATLAB/Simulink建立仿真模型,通过dSPACE进行编译并控制一台PMSM,比较了随机开关频率调制技术和死区补偿技术降低振动噪声的优缺点,提出一种混合随机开关频率死区补偿技术。试验结果表明,此方法综合随机开关频率调制技术和死区补偿技术的优点,能降低逆变器引入电流谐波引起的中低频振动噪声和逆变器开关频率与电流谐波相互作用引起的高频振动噪声。

| Abstract: | In order to reduce the vibration and acoustic noise of permanent magnet synchronous motor (PMSM) caused by inverter, first, the vibration and noise sources of PMSM caused by inverter were analyzed, and the simulation model build by MATLAB/Simulink was compiled by dSPACE to control a PMSM. Then, the advantages and disadvantages of random switching frequency modulation technique and deadtime compensation technique in reducing the vibration and acoustic noise were compared, and a method that mixed random switching frequency and deadtime compensation was proposed. Finally, the experimental results indicated that the proposed method could integrate the advantages of random switching frequency modulation and deadtime compensation technology, and reduced both the midlow frequency noise and vibration that was caused by current harmonics introduced by inverter and the high frequency noise and vibration that was caused by interaction of switching frequency of inverter and harmonic of current. |
