摘要

本文分析了传统脉宽调制降压-升压变换器的可靠性,评估了占空比、输入电压、输出功率、电压增益和持续时间对其可靠性的影响。这些分析是在连续和不连续的传导模式下进行的,并使用马尔可夫过程模型来获得结果。此外,还得到了该变换器相对于上述参数的平均失效时间。本文详细分析了不同评估参数下buck-boost变换器的可靠性。并编制了MATLAB软件的绘图,在各个运行状态下进行完整的评估。

Reliability Analysis of Buck-Boost Converter Considering the Effects of Operational Factors
In this paper, reliability of conventional pulse width modulation buck-boost converter is analyzed, where the effects of duty cycle, input voltage, output power, voltage gain and time duration are evaluated. These analyses are performed in both continuous and discontinuous conduction modes and Markov process model is utilized to obtain the results. In addition, mean time to failure of this converter is obtained with respect to the aforementioned parameters. In this paper, detailed analyses of reliability in buck-boost converter with different evaluation parameters are presented. Moreover, the plots of MATLAB software are prepared to have complete evaluation in each operating state.
