摘要

本文介绍了SEPIC DC-DC变换器的容差分析。在验证模型的基础上，确定了磁性元件和电容器的精度对所选电力电子器件输出指标的影响。在研究中，元件的值的变化选择成对进行，并且由于功率方案的特殊性，电感器L1和L2的变化是共同进行的，尽管它们之间选择了一个没有磁耦合的变体。这种对运行模式的影响的准确定量评估以表格形式和三维图形呈现。这样，在设计阶段就对电路元件进行了优化选择。本文的研究结果对SEPIC DC/DC变换器的稳定性和最优控制的综合研究也有一定的参考价值。

Tolerance Analysis of SEPIC DC-DC Converter

The paper presents tolerance analysis of SEPIC DC-DC converter. Based on a verified model, the influence of the accuracy of the magnetic components and the capacitors on the output indicators of the selected power electronic device is determined. In the study, the variation of the values of the elements was chosen to be performed in pairs, and due to the peculiarities of the power scheme the change of the inductors L1 and L2 is performed jointly, although a variant without magnetic coupling between them was chosen. Accurate quantitative assessment of this impact on the operating mode is presented in tabular form and through 3D graphs. In this way, the optimal selection of circuit elements is made at the design stage. The presented results are also useful for studying the stability and synthesis of optimal control of SEPIC DC/DC converter.
