AN IN-SITU ON-BOARD OFFLINE DIAGNOSTIC METHOD OF IGBT MODULES FOR BOND WIRE DEGRADATION WITHIN HIGH-POWER 3L-NPC CONVERTERS

An In-Situ On-Board Offline Diagnostic Method of IGBT Modules for Bond Wire Degradation Within High-Power 3L-NPC Converters

Performing in-situ diagnosis is a crucial task during routine inspections of high-power converter systems, such as mine hoist.This paper presents an on-board offline condition assessment method for bond wire degradation of high-power IGBT modules within three-level neutral-point clamped (3L-NPC) converter.This method is based on the High Voltage Tr

Changes in a Giant Iceberg Created from the Collapse of the Larsen C Ice Shelf, Antarctic Peninsula, Derived from Sentinel-1 and CryoSat-2 Data

The giant tabular iceberg A68 broke away from the Larsen C Ice Shelf, Antarctic Peninsula, in July 2017.The evolution of A68 would have been affected by both the Larsen C Ice Shelf, the surrounding sea ice, and the Hayward Sense nearby shallow seafloor.In this study, we analyze the initial evolution of iceberg A68A—the largest originating fro

Affinity purification of human factor H on polypeptides derived from streptococcal m protein: enrichment of the Y402 variant.

Recent studies indicate that defective activity of complement factor H (FH) is associated with several human diseases, suggesting that pure FH may be used for therapy.Here, we describe a simple method to isolate human FH, based on the specific interaction between FH and the hypervariable region (HVR) of certain Streptococcus pyogenes M Skateboards
