A Compact Single-Layer Balanced Phase Shifter With Wide Bandwidth and Uniform Reference Line

IEEE Access, 2020
A single-layer balanced phase shifter with uniform reference line is proposed to achieve the advantages of compact size and wide bandwidth compared with state-of-art single-layer balanced phase shifters.

Unfaithful Glitch Propagation in Existing Binary Circuit Models [PDF]

, 2013
We show that no existing continuous-time, binary value-domain model for digital circuits is able to correctly capture glitch propagation. Prominent examples of such models are based on pure delay channels (P), inertial delay channels (I), or the ...

A New Method of Transformer Short-Circuit Impedance Regulation Based on Magnetic Shunts

Energies
Short-circuit impedance is an important economic and technical index to test the cost, efficiency and operation safety of transformers. Increasing the short-circuit impedance of the transformer can reduce the influence of the transformer fault current on

Fault distance estimation method for two-phase short circuit in distribution networks considering photovoltaic output characteristics

International Journal of Electrical Power & Energy Systems
The widespread integration of photovoltaic generation systems (PVGSs) has significantly altered the fault characteristics of distribution networks, thus impacting existing methods for estimating fault distances. Moreover, the current methods often suffer

Study on Characteristic Parameters of Short-Circuit Impedance for a Four-Winding Inductive Filtering Transformer in Power System Supplying Nonlinear Loads

IEEE Access, 2019
Different from a three-winding transformer and ac passive filtering method, this paper proposes an inductive filtering (IF) method with a four-winding inductive filtering transformer (FW-IFT) for power system supplying nonlinear loads. Based on this, the
