摘要
在现代交流电机控制技术中,空间矢量脉宽调制(SVPWM)以其较高的直流电压利用率、较低的开关次数以及较少的谐波分量获得了越来越多的应用.为了能够将算法实现与工程实际更好地结合,本文提出了一种基于FPGA与DSP协同工作的SVPWM的FPGA解决方案.通过改变传统的SVPWM中零矢量的调制手段,在考虑IGBT工作频率的情况下,使得控制器能够自适应地调节零矢量的分配方式,同时谐波分量没有明显的增大.本文也介绍了这种新方法的FP-GA实现以及优化,使得整个方案在6000门以内的FPGA中得以实现.
In modern AC motor control techniques,SVPWM becomes popular due to its higher utilization of DC voltage,less switching frequency and lower harmonic components.According to such advantages,a controlling platform using both DSP and FPGA was raised and an FPGA-based SVPWM solution was proposed.Altering traditional zero vector modulation in SVPWM,a new algorithm that takes IGBT switching frequency into consideration was introduced,which can adaptively shift zero voltage modulation modes in SVPWM.Some optimization methods were also proposed while implementing his algorithm into hardware.
