摘要

非线性工作模式已经在一系列开关电源变换器(SPC)中观察了几十年。与消除这些区域的标准方法相反，我们获得了一组确保变换器产生鲁棒混沌振荡的参数。本文主要研究了次谐波和混沌模式对SPC主要转换特性的影响。数值计算和Spice模拟允许在对输出电压波纹和转换效率影响最小的情况下检测混沌区域。实验证明，在适当选择参数的情况下，SPC可以有效地用作混沌源，保证主要功能具有可接受的性能特性。

The Effects of Nonlinear Dynamics of Switching Power Supplies on the Power Conversion Characteristics

Nonlinear modes of operation have been observed in a range of switching power converters (SPC) for decades. Contrary to the standard approach to eliminate these regimes, we obtain the set of parameters that ensures the generation of robust chaotic oscillations of the converters. The current paper studies the effects of the subharmonic and chaotic modes on the main conversion characteristics of SPC. Numerical calculations and Spice simulations allow the detection of chaotic regions with the lowest influence on the output voltage ripples and conversion efficiency. It has been proved that with the appropriate choice of parameters, the SPC could be efficiently used as the source of chaos, ensuring the main functionality with acceptable performance characteristics.
