Design of Multi-channel PWM Controller Based on FPGA
Author(s): 
Pages: 72-76
Year: Issue:  4
Journal: Journal of University of Science and Technology of Suzhou(Engineering and Technology)

Abstract: 介绍了基于Altera公司的CycloneII系列现场可编程门阵列(FPGA)的多通道删控制器的设计实现方法.PWM控制的基本原理是控制开关占空比,在每个周期使开关变量的平均值与控制参考电压相等或成一定比例.利用FPGA的多通道并行控制功能,在控制电路输出频率不变的情况下,达到了可依据不同通道电压反馈值对多个通道进行占空比调整的设计要求.利用Altera公司的QuartusⅡ开发平台验证了设计方案...
