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 increment of the on-state voltage $V_{\mathrm {on}... https://www.freaknleather.com/product-category/optrel-papr-accessories-and-consumables/
