电流型Buck-Boost变换器的分岔频率相关性的验证

Verification of Frequency Correlation for Bifurcation of Current-Mode Controlled Buck-Boost Converters

导出

摘要 PWM型Buck-Boost功率变换器的频标可用于预测不同频率运行下的第一个分岔点。本论文首先推导出功率变换器新型频率的相关性。这是在高频工作下由仿真实验结果验证得到的。 The frequency scaling of pulse-width modulated Buck-Boost power converters can be used to predict the first bifurcation point at various frequency operations. This paper firstly derives the novel frequency correlation for the power converter. This is obtained by simulation experimental results at high-frequency operation.
