第七章，研究了离心风机蜗壳基频共振频率及高阶模态频率的确定方法，分析了蜗壳声阻抗及其对叶轮声辐射轮缘速度指数的影响，为风机的降噪提供了一种新的途径。

Digital simulation results show that when a step change in firing angle occurs, the first positive half-cycle time of VC will change suddenly and the subsequent electromagnetic transients appearing in the TCSC circuit will lead to overshoot and oscillations in the TCSC impedance. The range and duration of the oscillation will depend on the synchronization modes used and the manner in which the step change is introduced.

发现脉冲触发角阶跃变小时，电容电压的周期时间也突然变小，使得TCSC的导通角不会随着触发角的阶跃变化而发生突变，而是经过一个振荡过程逐渐达到稳态值，进一步揭示了电容电压同步方式下阻抗阶跃特性会出现过冲和振荡现象的原因。
