The purpose of this study is that we develop a single-phase, and a three-phase hybrid-modulated inverter with very low-distorted output voltage waveforms.The results are as follows:(1) A hybrid-modulated single-phase inverter. A novel hybrid-modulated inverter which has the feature of low distortion and low dv/dt has been successfully developed. The output voltage waveforms of the inverter was analyzed. It is found that the output voltage distortion decrease to less than fifty percent of that of conventional systems. The inverter developed was successfully applied to the 1/f fluctuation control of a small fan motor speeds which produces a comfortable wind similar to a natural, gentle wind.(2) A hybrid-modulated three-phase inverter. The output voltage waveforms of a multiple phase-staggered pulse width modulated inverter system which gives hybrid-modulated output voltage were analyzed. The characteristics of a three-phase induction motor fed by a hybrid-modulated inverter were discussed in time domain by modal approach.It is concluded that the proposed hybrid-modulated inverter system produces less distorted output voltage waveforms than conventional systems. The problem of electromagnetic interference(EMI), however, has not been solved.

这项研究的目的是我们开发了一个单相，并且具有非常低的输出电压波形的三相杂化逆变器。结果如下：（1）杂交型单相逆变器。一种新型的杂种调制逆变器，具有低失真和低DV/DT的特征。分析了逆变器的输出电压波形。发现输出电压失真降至常规系统的输出扭曲少于五十％。开发的逆变器已成功地应用于小型风扇电动机速度的1/F波动控制，该速度会产生类似于天然，柔和风的舒适风。（2）杂交的三相逆变器。分析了多个相干脉冲宽度调制的逆变器系统的输出电压波形，该逆变器系统得出了混合调节的输出电压。通过模态方法在时域讨论了由混合调节逆变器喂养的三相感应电动机的特征。它得出的结论是，所提出的杂化型逆变器系统比常规系统产生的造成的杂交逆变器系统会产生较小的失真输出电压波形。但是，电磁干扰（EMI）的问题尚未解决。
