摘要
提出了一种基于FPGA的高精度数字化电源控制器设计方案。从系统的角度分析了数字化PI调节算法、数字化PWM波形发生器和通讯模块等各部分的实现方式。利用FPGA和Verilog硬件描述语言在实验装置上进行了验证,实现了开关电源的数字化闭环控制。研究结果表明,同其它数字控制方式相比,本系统提高了PWM的精度和设计升级的灵活性。
This paper proposes a program of FPGA-based high-precision digital power supply controller and analyzes the implementation of each part of the system,including the digital PI regulator algorithm,the digital PWM waveform generator and communication module as viewed from the angle of the system.The paper verifies the result on the experimental platform with FPGA and Verilog hardware description language,and it achieves the digital closed-loop switching power supply control.Experimental results show that the system improve the accuracy of PWM and flexibility of the design in comparison with the other control pattern.
