摘要
根据Buck-Boost变换器的能量传输模式划分以及不同模式下的输出纹波电压表达式,建立了PSPICE图形文件,对其临界电感、输出纹波电压及其变化规律进行了仿真验证,仿真结果与理论计算吻合良好,验证了理论推导和分析的正确性,为变换器的分析和设计提供了一种有效实用的方法.
According to the classification of energy transmission mode and the output ripple voltage expressions in dif- ferent modes of Buck-Boost converter, an open loop mode of PSPICE graphic file was established. The critical induc- tance, output ripple voltage and its change rules were simulated. The simulation results are in good agreement with the theoretical analysis, showing the correctness of the theoretical analysis and deducing, which provides a powerful simula- tion tool for the analysis and design of converters.
