Abstract

In this paper, reliability of multi-phase coupled inductor based DC-DC boost converter is analyzed. The use of DC-DC converters in integrated power conversion systems has increased enormously in the recent times. A detailed study on the various reliability and loss factors in multi-phase interleaved converter is demonstrated. The continuous input and output current boost converter is studied with the PV converter at the input. A detailed study for a multi-phase converter is carried out with different numbers of converter units, different operating temperatures, and different irradiation levels of the PV converter. Extensive mathematical modeling and analysis of various converters in terms of failure rates are carried out summarizing the mean time to failure under the same operating scenarios. The MTTF of the system is estimated using Markov reliability models. The effect of the component selection and number of parallel paths on Mean time to failure are analyzed in detail. The concepts are verified through simulation studies using MATLAB-simulink.
