Improving the Electricity Quality by Means of a Single-Phase Solid-State Transformer
Designs, 2020 The paper describes the use of a single-phase three-stage solid-state transformer in networks with non-sinusoidal voltages in order to improve the quality of electricity. An active-inductive load was chosen as the load.

Finding, and Not Finding, “Higher Harmonic Flows” [PDF]
Acta Physica Polonica B Proceedings Supplement, 2013 Certain analysis methods have emerged recently that claim to reveal "higher harmonic flows" in more-central åcollisions at the RHIC and LHC. But pQCD calculations describe the same structures quantitatively.

EnergiesIn industrial plants with dynamically varying load profiles, the problem of increased charges for over-contracted reactive power consumption is very common. To eliminate these charges, reactive power compensation systems are used. This article presents a

The twisted higher harmonic signature for foliations
Journal of Differential Geometry, 2011 We prove that the higher harmonic signature of an even dimensional oriented Riemannian foliation of a compact Riemannian manifold with coefficients in a leafwise U(p,q)-flat complex bundle is a leafwise homotopy invariant. We also prove the leafwise homotopy invariance of the twisted higher Betti classes.

EnergiesAccording to standards, the harmonic content should be less than 5% at the time of calibration, while the calibration index proposed in this paper stipulates that the primary current amplitude of 1%~120% of the full range of the accuracy level reaches 0 ...
