Generalized Enhanced PWM for Multilevel Current Source Inverters
IEEE AccessIn power electronic converter topologies, when voltage and current stresses on power devices differ while operating at the same switching frequency and enduring these stresses for equal durations, power losses cannot be evenly distributed.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

A Gate Drive IC for Power Modules with Shoot-through Immunity [PDF]
Journal of the Korean Institute of Electrical and Electronic Material Engineers, 2009 This paper introduces a gate drive IC for power modules with shoot-through immunity. A new approach uses a bootstrap diode as a high-side voltage bias and a level shift function at the same time. Therefore, the gate drive circuit becomes a simple and low-cost without conventional level shift functions such as HVIC(High-Voltage IC), optocoupler and ...

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Dissipation Loop for Shoot-Through Faults in HVDC Converter Cells
2018 International Power Electronics Conference (IPEC-Niigata 2018 -ECCE Asia), 2018 Converter cells for HVDC applications store large amounts of energy. This energy might be dissipated in a very short time in case of a shoot-through fault. Measures to avoid shoot-through or handle the extreme currents during a fault and prevent damage from neighboring components are essential to ensure a continued operation of the converter.
