Y-Source Two-Stage Matrix Converter and Its Modulation Strategy

IEEE Access, 2020
Aiming at the defect of low voltage transfer ratio of two-stage matrix converter(TSMC), the proposed topology combines the Y-source network with the TSMC to form the Y-source two-stage matrix converter(YSTSMC) in this paper, and proposes its modulation ...

A Transient Damping Improvement Strategy for Enhancing Grid-Connected Active Power Response Performance of VSG

Energies
The given power and grid frequency disturbances can cause transient oscillations and steady-state deviations in the output power of a virtual synchronous generator (VSG), which can be effectively addressed by adding transient damping.

Associated charged Higgs and W boson production in the MSSM at the CERN Large Hadron Collider

, 2008
We investigate the viability of observing charged Higgs bosons (H^+/-) produced in association with W bosons at the CERN Large Hadron Collider, using the leptonic decay H^+ -> tau^+ nu_tau and hadronic W-decay, within different scenarios of the Minimal ...
