摘要
以10 A Buck开关电源为例进行建模。针对建模中存在的穿越频率低、相位裕度差及输出电压纹波小等缺点,设计相应的PID网络。通过使用Matlab软件进行仿真,对比补偿前、补偿后的变化,证明了此补偿网络可以解决建模中存在的相关问题。
Taking 10 A Buck switching power supply as an example to model.Aiming at the shortcomings of low crossover frequency,poor phase margin and small output voltage ripple in the modeling,the corresponding PID network is designed.By using Matlab software to simulate and compare the changes before and after compensation,it is proved that this compensation network can solve the related problems in modeling.
