基于电感电流路径建模的交错式图腾柱PFC变换器开路故障诊断

Online fault diagnosis is crucial for ensuring reliable operation in interleaved totem-pole power factor correction converters. In this article, a fault diagnosis and localization strategy for open-circuit faults based on the inductor current path modeling with diagnostic interval threshold is proposed. By analyzing the behavior of the inductor current and the input voltage phase during open-circu...
