| 中文摘要 | 空间矢量脉宽调制(SVPWM)和单周控制(one-cycle control)是目前最常见的两种脉宽调制(PWM)技术。传统观点认为,它们是不同的PWM发生技术,即相同的参考波得到的触发脉冲不相同。文中以四桥臂STATCOM的主电路结构为例,经过数学推导,证明了下述结论:就二者发出的触发脉冲的结果而言,SVPWM与单周控制算法是等效的,而且单周控制的计算代价明显小于SVPWM。此外,通过对一个由清华大学独立研制的四桥臂STATCOM进行仿真,对理论结果进行了验证。进一步解释了这两种PWM技术的物理本质,进而推出所有的PWM方法经过适当的控制,都可以得到相同的触发脉冲。; Space vector pulse width modulation (SVPWM) and one-cycle control are two of the most popular pulse width modulation (PWM) strategies. It is commonly believed that they are totally different PWM methods, and the PWM waveforms generated by these two methods are different even with the same reference waveform. This paper proves that SVPWM and one-cycle control are identical as far as their PWM results are concerned by deduction on a 4-leg STATCOM structure. Simulation results performed on a 4-leg STATCOM developed by Tsinghua University are also given to confirm the conclusion. This paper further explains the essence of PWM and concludes that all kinds of PWM methods will produce the same results with proper control strategies.; 国家自然科学基金资助项目(50377018) |
