Liang Zhou, member IEEE and YiFeng Wu, member IEEE Transphorm, Inc. 75 Castilian Dr., Goleta, CA, 93117 USA [email protected] Abstract: This paper presents a true bridgeless totem-pole Power-Factor-Correction (PFC) circuit using GaN HEMT. Enabled by a diode-free GaN power HEMT bridge with low reverse-recovery charge, very-high-efficiency single-phase AC-DC conversion is realized using a t...

The TOTEM (TOTal cross section, Elastic scattering and diffraction dissociation Measurement at the LHC) experiment, located interaction point 5 of LHC, has measured total, elastic inelastic proton-proton crosssections, using a luminosity independent method, based on optical theorem, in center-of-mass energy range from 2.76 to 13 TeV. was investigated wide squared four-momentum transfer |t| allo...
