在一些高性能的运动控制系统中，需采用处理速度快、处理数据量大、高可靠性和高实时性的底层信号算法。通过对空间矢量脉宽调制（SVPWM）原理和算法的分析，提出一种基于现场可编程门阵列（FPGA）的SVPWM信号发生器的设计方案，介绍SVPWM模块的FPGA生成方法，并在FPGA上得到了具体的验证和实现。该设计利用SVPWM算法和FPGA的优点，使SVPWM算法不仅易于实现数字化和实时控制，而且直流电压利用率高、控制性能好，对设计高性能的运动控制系统有重要的应用价值。%A fully digital scheme of SVPWM generator based on FPGA is proposed in the paper. The method of generating SVPWM module of FPGA is introduced,which is verified in FPGA. Taking advantages of the SVPWM and FPGA, the scheme not only achieves simpler algorithm, easier real-time control operation, but also gains higher DC voltage utilization and perfects control performance. The scheme has application value in the high-powered motion control system.
