Harmonic correction in power supplies feeding non-linear loads [PDF]
, 2014 This paper focuses on the design of an electronic circuit which can be used in conjunction with the power supplies used at the input of non-linear loads (computers, TV sets, etc.) in order to filter out the input current harmonics in such loads.

Third harmonic current minimization using third harmonic blocking transformer
Indonesian Journal of Electrical Engineering and Computer Science, 2022 Zero sequence blocking transformers (ZSBTs) are used to suppress third harmonic currents in 3-phase systems. Three-phase systems where single-phase loading is present, there is every chance that the load is not balanced. If there is zero-sequence current due to unequal load current, then the ZSBT will impose high impedance and the supply voltage at the

Non-sinusoidal current and current reversals in a gating ratchet [PDF]
, 2015 In this work, the ratchet dynamics of Brownian particles driven by an external sinusoidal (harmonic) force is investigated. The gating ratchet effect is observed when another harmonic is used to modulate the spatially symmetric potential in which the ...

Harmonic feature of 27.5 kV traction power system in a Chinese high‐speed railway
IET Electrical Systems in Transportation, 2022 The key to controlling harmonics in high‐speed railways is to get information on its harmonic feature. In this study, a continuous 24 h harmonic observation is carried out in Ji'an West traction substation of a typical Chinese high‐speed railway. In both

Coordinated control for harmonic mitigation of parallel voltage-source inverters
CES Transactions on Electrical Machines and Systems, 2018 The increasing use of power electronic devices can deteriorate the power quality by introducing voltage and current harmonics. In islanded microgrids, the presence of nonlinear loads can distort the point of common coupling (PCC) voltage, while the dead ...

The Impact of an Overlaid Ripple Current on Battery Aging: The Development of the SiCWell Dataset
Batteries, 2022 Fast-switching semiconductors induce ripple currents on the high-voltage DC bus in the electric vehicle (EV). This paper describes the methods used in the project SiCWell and a new approach to investigate the influence of these overlaid ripples on the ...

Directed harmonic currents near hyperbolic singularities [PDF]
Ergodic Theory and Dynamical Systems, 2017 Let $\mathscr{F}$ be a holomorphic foliation by curves defined in a neighborhood of $0$ in $\mathbb{C}^{2}$ having $0$ as a hyperbolic singularity. Let $T$ be a harmonic current directed by $\mathscr{F}$ which does not give mass to any of the two separatrices. We show that the Lelong number of $T$ at $0$ vanishes.

A Methodology for High-Power Drives Emulation Using a Back-to-Back Configuration
IEEE Access, 2022 Validation of high-power converters at the development stage often cannot be performed using the real load. A testbench consisting of the Equipment Under Test (i.e., tested power converter) and an auxiliary power converter, preferably using power ...
