摘要
对目前主流电压源型拓补结构的高压大功率变频器的的平均无故障时间(MTBF)进行了相对性的分析和比较。该比较是基于相同的故障定义、计算方法和环境假设,结合考虑主要器件的负荷强度和现场经验数据,计算出变频设备整体的可靠性指标。同时分析了不同拓补结构的冗余设计能力及其对变频器系统可靠性的影响。
Compare the MTBF of high power medium voltage drive systems from mainstream voltage source topologies.This comparison is based on the same definition,calculation method and assumptions,considering components stress and field data.And the capability of implementing redundancy by the topologies addressed as well as its impact on reliability is analyzed.
