Grid-Connected Inverter Based on a Resonance-Free Fractional-Order LCL Filter

open access: yesFractal and Fractional, 2022
The integer-order LCL (IOLCL) filter has excellent high-frequency harmonic attenuation capability but suffers from resonance, which causes system instability in grid-connected inverter applications. This paper studied a class of resonance-free fractional-

Membrane capacitive memory alters spiking in neurons described by the fractional-order Hodgkin-Huxley model. [PDF]

open access: yesPLoS ONE, 2015
Excitable cells and cell membranes are often modeled by the simple yet elegant parallel resistor-capacitor circuit. However, studies have shown that the passive properties of membranes may be more appropriately modeled with a non-ideal capacitor, in ...

Energy Consideration of a Capacitor Modelled Using Conformal Fractional-Order Derivative

open access: yesKocaeli Journal of Science and Engineering, 2022
Fractional order circuit elements have become important parts of electronic circuits to model systems including supercapacitors, filters, and many more. The conformal fractional derivative (CFD), which is a new basic fractional derivative, has been recently used to model supercapacitors successfully.
