一种CLLC变换器开路故障检测与定位新方法

This article proposes a novel method for open-circuit fault detection and localization (OCFDL) in CLLC converters, which is characterized by high speed and independence from output load. The precise location of the open-circuit fault (OCF) is rapidly identified using voltage waveforms across the terminals of the resonance tank capacitor. After fault detection (FD), the converter employs a backup l...
