| 摘 要： | 根据Buck变换器的小信号模型,用两种设计方法设计了平均电流控制的Buck型双环开关调压系统的数字双环控制器;然后给出了仿真分析;最后以TMS320F28335为DSP芯片搭建实验电路,通过实验对两种控制方式的控制效果进行了比较.仿真及实验结果表明,将频域法设计的连续域的补偿网络传递函数离散化得到离散域的补偿网络传递函数,平均电流控制的Buck型双环开关调压系统具有更好的响应特性.

| Abstract: | According to the small signal model of Buck converter,this paper uses two designing methods to design the digital double-loop controller of the Buck double-loop switch voltage regulation system with average current control.And then a simulation analysis is given.Finally,TMS320F28335 is used as the DSP chip to build the experimental circuit,and the controlling effects of the two control methods are compared experimentally.Simulation and experimental results show that when the compensation network transfer function of the continuous domain designed by frequency domain method is discretized to obtain the compensation network transfer function of discrete domain,the Buck double loop switching voltage regulating system with average current control will have better response characteristics. |
