Development of Fractional Order Modeling of Voltage Source Converters

IEEE Access, 2020
This paper proposes a mathematical fractional order modelling of Voltage Source Converters (VSC). Fractional behaviour helps to model and describe a real object more accurately than the integer order model.

Active realization of fractional order Butterworth lowpass filter using DVCC

Journal of King Saud University: Engineering Sciences, 2020
This paper presents an active realization of fraction order Butterworth lowpass filter using a differential voltage current conveyor (DVCC) and two fractance devices (FDs). Initially, the DVCC based fractional order system transfer function is developed.

Analysis and Verification of Identical-Order Mixed-Matrix Fractional-Order Capacitor Networks [PDF]

2018 14th Conference on Ph.D. Research in Microelectronics and Electronics (PRIME), 2018
In the open literature while capacitors are introduced with -90 degrees phase angle, here we described our fabricated polymer composite, mixed matrix, as a fractional- order capacitor (FoC). The effect on phase and pseudo- capacitance using a detailed numerical and experimental study of circuit network connections of three identical-order FoCs is shown.

Fractional modelling and simulation for single-phase PWM rectifier

The Journal of Engineering, 2018
Modelling and analysis of single-phase PWM rectifier are usually based on integer order calculus theory, regardless of the fractional characteristics of inductors and capacitors, which will bring a deviation with the real system.
