摘　　要：针对传统采样型正弦脉宽调制技术各有优缺点的问题,引出了新型线性组合采样法。该方法综合了对称规则采样法和不对称规则采样法的优点,既具有对称规则采样法的采样次数少、占用内存资源少、实时性好的优点,又具有不对称规则采样法的谐波含量低的优点。基于数字信号处理器,开发了线性组合采样法的软件系统。以三菱IPMPM25RLA120为核心,开发了线性组合采样法变频调速的硬件系统。实验结果验证了新方法的优越性,同时也验证了所开发的实验平台的可用性。In view of the advantages and disadvantages of traditional sampling sinusoidal pulse width modulation,a new linear combination sampling method is proposed.The method combined the advantages of the symmetric rule sampling method and the asymmetric rule sampling method,which not only has the advantages of less sampling times,less memory resources and good real-time performance,but also has the advantages of the asymmetric rule sampling method with low harmonic content.Based on digital signal processor,the software system of linear combination sampling SPWM is developed.Taking Mitsubishi IPM PM25RLA120 as the core,the hardware system of linear combination sampling method is developed.The experimental results verified the superiority of the new method and the usability of the experimental platform.
