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.
