开关电源稳定性和控制环路补偿研究

Switching power supply stability and control loop compensation research

文章对影响开关电源稳定性能的内部模块电路和工作环路的不稳定因素的分析,对其时域和频域的分析以及伯德图的测量得到功率变化部分的传递函数,引入极点和零点对其控制环路的补偿的研究。

In this paper, of internal module affect the stability of switching power supply circuit and the work loop unstable factors in the analysis, its time domain and frequency domain analysis and Bode plot measuring part of the trans- fer function of the power change, the introduction of the pole and zero its control loop compensation.
