Performance and Stability Analysis of Series-Cascaded, High-Gain, Interleaved Boost Converter for Photovoltaic Applications

Power Electronics and Drives, 2018
Interleaved boost converters (IBCs) are cascaded in parallel in most of the applications. This novel approach connects IBC in series cascade. The IBC has an optimal operating duty cycle of 0.5.

Knowledge-graph-enhanced and LLM-guided fault diagnosis for VSC-HVDC systems [PDF]

AIP Advances
Accurate fault diagnosis in voltage-source-converter high-voltage direct-current (VSC-HVDC) systems is vital for grid stability, yet existing data-driven methods often lack interpretability and robustness under complex operating conditions.

Voltage graphs, weight systems and odd symmetry

Discrete Mathematics, 2001
A knot in the three-sphere \(S^{3}\) is called invertible if there exists an orientation preserving homeomorphism of \(S^{3}\) which takes the knot to itself with reverse orientation. It is an interesting problem whether Vassiliev invariants can detect the invertibility of a knot.
