摘要
文章提出了一种改进型正弦波脉宽调制（ＳＰＷＭ）对称规则算法。基于该算法，设计了高精度ＳＰＷＭ实时控制器。这种以微处理器为核心的实时控制器可满足实时性要求和较高的精度要求，其硬件设计也充分体现了可靠性和稳定性。最后讨论了抗干扰措施、谐波修正等问题。
In this paper, the Sine Pulse Width Modulation(SPWM) technology is investigated, and an improved SPWM algorithm is presented. Based on this algorithm the SPWM real time controller with high precision is designed. Both software and hardware of this controller are of high reliability and stability. The anti disturbance measure and harmonic modification are also discussed.
