摘要

本文主要研究非理想反馈电路开关电源变换器的稳定性问题。采用完全分岔图的方法,利用离散时间建模方法,研究了补偿型升压变换器控制电路中引入延迟引起的非线性效应的相互作用。针对实际相关的时滞值,探讨了利用补偿坡道扩大稳定区域的有效性。

On the effectiveness of application of compensation ramp in switching power converters with delays
The current study is dedicated to the investigation of stability issues occurring in switching power converters with non-ideal feedback circuitry. The interaction of nonlinear effects caused by the introduction of delay in the control circuitry of the compensated boost converters is studied by means of complete bifurcation diagrams, exploiting discrete-time modeling approach. The effectiveness of widening the stability region using the compensation ramp is explored for practically relevant values of delays.
