switch angle中文什么意思
例句與用法
- The performance of the electric vehicle is improved greatly in which the harmonic wave of output voltage , power loss and torque pulsation of the system are decreased by controlling the switch angles
它運(yùn)用規(guī)則采樣法產(chǎn)生正弦脈寬調(diào)制波，通過開關(guān)角的控制抑制逆變器輸出電壓中的諧波分量，降低了電動(dòng)機(jī)的損耗和轉(zhuǎn)矩脈動(dòng)，使電動(dòng)車的運(yùn)行性能得到了較大改善。 - The main studying contents and achievements in this dissertation are presented as follows . based on the analysis of the selective harmonic elimination pwm mathematical model , an equivalent newton iteration solving method about the switching angles nonlinear transcendental equation set is presented . the algorithmic convergence time is enormously reduced and the algorithmic convergence ability is highly increased
本文的主要研究內(nèi)容和成果如下：通過對(duì)單相特定消諧pwm數(shù)學(xué)模型的分析，提出了關(guān)于開關(guān)角非線性超越方程組的等效轉(zhuǎn)化牛頓迭代解法，極大地縮短了算法收斂時(shí)間，提高了算法的收斂性，為特定消諧pwm開關(guān)角的工程計(jì)算提供了新的方法。
