摘要
文中在深入分析SVPWM原理的基础上,提出了一种SVPWM的简化实现算法,该算法无需进行复杂的三角函数运算,只需通过简单的四则运算即可实现扇区判断和有效矢量作用时间的计算。分析了该简化算法的实际物理意义,并在基于STM32F407微处理器的永磁同步电机控制器中验证了该简化算法的可行性。
On the basis of deeply analyzing the principle of SVPWM, this paper presents a simplified algorithm of SVPWM, which can be achieved by simple four operations other than complicated trigonometric function calculation to realize the calculation of the time of sector judging and effective vector operation. In this paper, the practical physical meaning of the simplifiedalgorithm is analyzed, and the feasibility of the proposed algorithm is verified by the permanent magnet synchronous motor controller based on STM32F407 microprocessor.
