摘要
文中详细讨论了开关电源输出特性与反馈回路直流增益的关系。给出了一种通过偏置TL431来减小静态误差和输出阻抗的方法。并以反激式开关电源为例,详细地介绍了该方法的应用。实验证明,该方法可靠、可行。
The relationship between output character of Switching Mode Power Supply （SMPS） and DC gain in feedback loops is discussed. A method to reduce the static error and output impedance by biasing the TL431 is given. Taking the fly back SMPS as an example, the application of this method is introduced in detail. As the result shows, this method is reliable and feasible.
