Boost power factor correction converter with adaptive harmonic compensation control

IET Power Electronics, 2023
In low‐voltage distribution systems, the increased penetration of power electronic devices leads to the decentralization of harmonic sources, which puts the sensitive loads or communication systems in the risk status. The conventional methods of point‐to‐

Fitting formulae of the reduced-shear power spectrum for weak lensing

, 2010
Context. Weak gravitational lensing is a powerful probe of large-scale structure and cosmology. Most commonly, second-order correlations of observed galaxy ellipticities are expressed as a projection of the matter power spectrum, corresponding to the ...
