Or 2, the extended and rapid octave passages of such pieces as Chopin's Polonaise in A Flat, opus 53, or Liszt's Les Funerailles.

这些钢琴家认为：肌肉疲劳是不可避免的：如当弹奏肖邦练习曲作品10号1或2时，长期和快速的八度音节弹奏如肖邦降A大调波洛涅兹舞作品53号或李斯特 Les Funerailles。

In this paper, the basic principle and the power factor of conventional SERDS are discussed. Aiming at its shortage of low power factor, boost chopper type SERDS is adopted. The equivalent circuit of the new scheme is built up, and then vector diagram is used to analyze the power factor of the system, also the harmonic distortion of the system is discussed. The experiment device is established base on a 380F/7.5 kW induction motor and a passive soft switching scheme is applied in order to improve the working condition of IGBT. At last, the experimental results are shown.

本文在分析传统串级调速原理的基础上，对系统的功率因数进行分析；针对传统串级调速系统功率因数低的缺点，采用升压斩波式串级调速系统加以改进；建立了升压斩波式串级调速系统的等效电路并采用向量图法对该系统的功率因数进行详细分析；分析了系统的谐波情况；构建了以7.5kW／380V电机为调速对象的升压斩波式串级调速系统实验装置，给出相应的实验结果；针对斩波器中IGBT处于硬开关状态的缺点，应用无源无损软开关技术予以改善，包括对软开关电路工作原理的分析、参数的设计并给出相应的实验结果。
