With the increasing use of power electronic converters, the reliability studies of these converters are essential. The most important factor in increasing the reliability of power converters is their structures. In this paper the reliability evaluation of a DC–DC converter with various connections including single‐phase, interleaved, and parallel‐input and series‐output (PISO) topologies is presented. In the first view, it seems that the interleave topology has high reliability, but considering the more presented detailed indexes, it is identified that the PISO structure has a higher reliability than the interleave structure. In this paper for better evaluation, the various topologies are considered which operate at full rated power and half power. To calculate the reliability of the converters the important parameters such as the thermal and electrical stresses of elements are considered. The Markov model is used to evaluate the reliability. In order to verify the presented studies and analysis, the DC–DC converters with single‐phase, interleaved, and PISO have been implemented. The experimental results show that the PISO topology has higher reliability.

“…In [25], the improving effect of decentralized control architecture on system reliability is validated by using Markov chain models. On the other hand, [26] investigates the reliability on device level, AC-DC converters, under different topological structures and modulation strategies. Study [27] aims to assess overall reliability of an islanded MG through a holistic operation failure rate model.…”
