SVPWM（空间电压矢量脉宽调制）控制存在着包括数学模型的构建、坐标变换、解耦控制及控制算法实现等多个难点,这些给学习和研究SVPWM控制技术的师生带来了很大的困难。本文在SVPWM控制技术的研究和应用中,总结出了三个容易被忽略的三角恒等式,为三相整流器数学模型构建、Park坐标变换及空间电压矢量合成的理解和实现提供帮助。

There exist many difficulties such as construction of mathematical model, coordinate transformation, decoupling control and SVPWM algorithm when studying SVPWM control technology. Three trigonometric identities are extracted from our research on SVPWM and proved to help the teachers and students understand how to construct the three-phase rectifier model, carry out park transformation and compose the space voltage vector.
