Digital V2 Control of DC-DC Switching Converters Based on Leading-Edge Modulation

  • 摘要: 为促进数字控制技术的发展,基于数字控制器的基本功能模块和V2控制方法的基本原理,提出了基于前缘调制的数字V2控制算法,并探讨了该算法消除次谐波振荡的原理.基于MATLAB仿真软件平台,对采用数字V2控制算法的开关变换器进行了计算机仿真,并采用FPGA(现场可编程门阵列)作为硬件平台进行了实验.在相同的Buck变换器上,将采用数字V2控制算法与电压型控制算法的仿真结果和实验结果进行了比较,结果表明,采用数字V2控制算法可提高开关变换器的动态性能.
