In general, formed components are lightweight as well as highly economic and resource efficient. However, forming-induced ductile damage, which particularly affects the formation and growth of pores, has not been considered in the design of components so
Abstract: A full-bridge diode-clamped multilevel LLC resonant converter suitable for power conver- sion systems that use high input voltage, such as railway vehicles, is proposed in this paper. In order to eliminate the voltage deviations of the capacitors connected in series to the high voltage...
Based on the previous literature, these unstable phenomena in high-speed railway system can be summarized as follows: • Harmonic Resonance The frequency of harmonic resonance usually ranges from a few hundred Hertz to kilohertz. During the train operation, high-frequency harmonic components are ...
