Buck Inverter without Shoot through
IET Power Electronics, 2017 A new buck inverter without shoot‐through problem is presented and analysed in this study. The traditional dual‐buck inverter has been proposed to solve the shoot‐through problem of bridge‐type inverters, eliminate the dead‐time effect and improve the reliability along with the conversion efficiency. However, the existing dual‐buck inverter is prone to

Analysis and mitigation of dead time harmonics in the single-phase full-bridge PWM converters with repetitive controllers [PDF]
, 2018 In order to prevent the power switching devices (e.g., the Insulated-Gate-Bipolar-Transistor, IGBT) from shoot through in voltage source converters during a switching period, the dead time is added either in the hardware driver circuits of the IGBTs or ...

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.

Temperature and switching rate dependence of crosstalk in Si-IGBT and SiC power modules [PDF]
, 2015 The temperature and dV/dt dependence of crosstalk has been analyzed for Si-IGBT and SiC-MOSFET power modules. Due to a smaller Miller capacitance resulting from a smaller die area, the SiC module exhibits smaller shoot-through currents compared with ...

Crosstalk in SiC power MOSFETs for evaluation of threshold voltage shift caused by bias temperature instability [PDF]
, 2019 Threshold voltage drift from Bias Temperature Instability is known to be a reliability concern for SiC MOSFETs. Negative bias temperature instability (NBTI) results from positive charge trapping at the gate dielectric interface and is more problematic in
