摘要
以电压模式控制单级反激变换器为研究对象,在简化的离散时间模型基础上,运用非线性动力学对其稳定性问题进行了探讨,基于特征值的稳定性分析和仿真结果能够较好的吻合,并与相同运行点的直流变换器的仿真进行了比较.
The closed-loop stability characteristics of single-stage flyback converter under voltage con-trol is investigated based on the simplified discrete-time model using nonlinear dynamics method. The stabilityanalysis based on the eigen value of Jacobin matrix is in relatively good agreement with the simulation results.And the comparison with the corresponding DC converter is provided.
