In this article, the behavior of short-circuit (SC) caused by incorrect gate signals in bridge structures is analyzed detail semiconductor device theory, experimentations, and physics-based simulations, which has rarely been studied before. The voltage redistribution phenomenon associated dynamic avalanche failures are discovered. An experimental platform designed built to reproduce SC conditions structures. Both theory results reveal that bus <italic...
In recent years, modular multilevel converters (MMC) have been widely used in far seas offshore wind power delivery scenarios. The converter valve of the MMC project is arranged on platforms, and its large volume weight lead to high construction costs difficulties platforms. use 2nd frequency circulating current injection strategy can reduce voltage fluctuation sub-module capacitance under steady-state conditions, thereby reducing value overall converter. However, actual selection should...
The predecessor of China Optics was and Applied Digest, which founded in 1985. At that time, it the only retrieval journal field optics China. end 2008, Digest renamed
