Fault Detection of High-Speed Train Wheelset Bearing Based on Impulse-Envelope Manifold by Zhe Zhuang, Jianming Ding, Andy C. Tan, Ying Shi, Jianhui Lin

“…The analyzed results based on simulations, experimental tests, and practical applications show that (1) the impulse-envelope manifold with both isometric mapping (Isomap) and locally linear coordination (LLC) can be successfully used to extract the intrinsic envelope of the impulses where local tangent space analysis (LTSA) fails to perform and (2) the impulse-envelope manifold with Isomap outperforms those with LLC in terms of strengthening envelopes and the number of extracted harmonics. The proposed impulse-envelope manifold with Isomap is superior in extracting the intrinsic envelope, strengthening the amplitude of intrinsic envelope spectra, and enlarging the harmonic number of fault-characteristic frequency. …”

A Design Procedure and Control Method for Improving Efficiency of a Family of Resonant Converters Over Wide Operating Conditions by Jasem Shahsevani, Reza Beiranvand

“…However, low efficiency under light-load or no-load conditions is one of their main challenges, which arises when their switching frequencies deviate significantly from their resonance frequencies during output voltage regulation, resulting in high circulating currents and switching harmonics values. Here, a novel design procedure and control method are proposed for the resonant converters, which have parallel components in their resonant tank circuits to address their light-load or no-load low-efficiency issues. …”
