Application of FPGA in high-power multiphase variable speed drives
Author(s): 
Pages: 51-55
Year: Issue:  6
Journal: Electric Machines and Control

Keyword:  变频调速脉冲宽度调制现场可编程门阵列故障保护;
Abstract: 针对大功率多相感应电机变频调速系统中PWM信号通道多和难同步的问题,提出一种基于PWM IP核的多路PWM发生器的设计方法,利用搭积木的方法可方便构建任意路PWM发生器.多路PWM发生器通过采用同一时基和各自独立的控制寄存器,可实现PWM信号的严格同步和不同调制策略.利用FPGA的硬件并行性,实现高性能的三角载波发生器和高可靠性的故障保护.基于FPGA和DSP构建一个多相变频调速系统硬件平台,在一...
