基于SOPC的SVPWM信号发生器的实现

本文提出了一种基于SOPC技术的SVPWM信号发生器的实现策略,采用Verilog HDL定制系统需要的外设,并在FPGA芯片内部嵌入一个NiosⅡ处理器软核,从而采用软硬件协同工作的方式来实现SVPWM调制算法。该方案结合了SVPWM与SOPC技术的优点,在高性能的控制系统中有重要的应用价值,为设计高性能的电机控制系统提供了一种全新的实现方法。最后在Altera公司CycloneⅢ系列的EP3C25 FPGA芯片上进行实验,验证了系统的可行性与正确性。

Implementation of Space-Vector-PWM Based on SOPC

This paper presents a new realization of SVPWM based on SOPC technique. IP core was designed by Verilog HDL and a processor Nios II was embedded in FPGA chip,so software and hardware can be combined to realize this SVPWM control system. This scheme contains the advantages of SVPWM generator and SOPC technique,thus being important for high-powered control system,and a new way for the design of high-performance motion control systems is provided.The correctness and feasibility of this control system was verified using a EP3C25 FPGA chip from Altera,Inc.
