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 ...

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.
