摘要

高增益直流-直流转换器是可再生能源系统（RES）和电动汽车系统的关键部分。为了保证可再生能源系统的长期运行，需要对这些高增益转换器的可靠性进行评估。本文介绍了非隔离式高增益交错直流-直流转换器的可靠性分析。分析主要依靠计算平均故障间隔时间（MTBF）。根据军用手册 (MIL-HDBK-217) 标准，进行了可靠性计算。对转换器各组件的应力系数和预测故障率进行了评估并制成表格。对 1.5 kW 硬件原型进行了可靠性评估。根据可靠性评估结果，推出了具有更长工作寿命的可靠转换器。

Reliability evaluation of non-isolated high gain interleaved DC-DC converter

A high gain DC-DC converter is the crucial part in renewable energy systems (RES) and in electric vehicular systems. The reliability of those high-gain converters needs to be assessed for the long-term operation of renewable energy systems. This article presents the reliability analysis of non-isolated high gain interleaved DC-DC converter. The analysis primarily relies on calculating the mean time between failures (MTBF). Based on military handbook (MIL-HDBK-217) criteria, the reliability calculation is performed. Stress factors and predicted failure rate for each component of presented converter is evaluated and tabulated. Reliability evaluation is performed for 1.5 kW hardware prototype. Based on reliability evaluation results, a reliable converter with better operating life time has been introduced.
