A testing method for evaluating shoot-through immunity of IGBTs in an inverter

Microelectronics Reliability, 2021
The shoot-through fault in inverters results from a gate noise voltage of power semiconductor switches including IGBTs. Testing the gate voltage under the high-speed switching event is important to evaluate immunity to the fault as well as to analyze the mechanism of the fault.

Shoot yield drives phosphorus use efficiency in Brassica oleracea and correlates with root architecture traits [PDF]

, 2009
The environmental and financial costs of using inorganic phosphate fertilizers to maintain crop yield and quality are high. Breeding crops that acquire and use phosphorus (P) more efficiently could reduce these costs.

A Gate Drive IC for Power Modules with Shoot-through Immunity [PDF]

Journal of Korean Institute of Electrical and Electronic Materials 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 ...

A quantitative harmonics analysis approach for sinusoidal pulse‐width‐modulation based Z‐source inverters

IET Power Electronics, 2022
The shoot‐through (ST) states are essential for the operation of sinusoidal pulse‐width‐modulation (SPWM) based Z‐source inverters. However, the insertion of shoot‐through state unavoidably leads to output harmonics which is greatly affected by its ...

Improving culture initiation of mature oak shoots through use of silver thiosulfate

Applications in Plant Sciences, 2022
AbstractPremiseOf the approximately 430 species of oaks (Quercus spp.) that have been assessed, 31% are threatened with extinction and in need of safeguarding. However, oak seeds cannot be seed banked, and thus rely on alternative strategies such as in vitro culture for ex situ conservation.
