Analysis of DC-DC Boost Converter Using Dual Current Flows Kumar Biswal, Arya Suman Pattnaik, Sanjeeb Kumar Kar, Akshya Kumar Patra 3rd Odisha International Conference on Electrical Power Engineering Communication and Computing Technology Odicon 2024, 2024 Power-management integrated circuits (PMICs) are using more affordable tiny inductors as a result of the growing need for small, low-cost electronics. However, low efficiency results from a small inductor's parasitic DC resistance (RDCR), which shortens the battery's lifespan and may also contribute to temperature issues with mobile devices. Because of the large inductor current, these problems are especially problematic when using a typical boost converter (CBC) to attain a high output voltage. Furthermore, other problems deteriorate with increasing output voltage, including considerable output voltage ripple, conversion-ratio limits, and overlap losses. This study presented a high-voltage boost converter with dual-current flows (HVDF) to address these problems.
Stability Analysis of Fractional-Order PID Controller Kumar Biswal, Sumit Swain, Arya Suman Pattnaik 2023 IEEE 3rd International Conference on Smart Technologies for Power Energy and Control Stpec 2023, 2023 The PID controller is more adaptable and provides the chance to improve the ability to modify the control system. It is compact and simple, but the analog perceptive of the fractional order (FO) system is very difficult to adapt to changes. Incidentally, FOPID has more degree of freedom than conventional PID controller. It can be expected that FOPID can provide better performance with the appropriate selection of control parameters. However, with so many parameters to be fixed, the related interaction problem will be much more difficult to deal with. The FOPID controller was tuned with Ziglar Nicholas Tuning and TyreusLuyben tuning and then compared with Particle Swarm Optimisation (PSO) technique. It is motivated to improve the strategic FOPID optimization process to achieve specific performance of the controller.
Realization of A Bessel Bandpass Filter Using Fractional-Order Approach Kumar Biswal, Sumit Swain, Sanjeeb Kumar Kar 2023 International Conference in Advances in Power Signal and Information Technology Apsit 2023, 2023 The paper deals with the design, analysis and investigation of the fractional-order Bessel bandpass filter. The filter comprises of two fractional-capacitors FC1 and FC2 bearing exponents $\\alpha$ and $\\beta$ respectively varying from 0.1 to 1.0 with a step of 0.1. Here, both the frequency and the time domain analysis have been demonstrated. It has been found that, the proposed filter in fractional-domain provides very high bandwidth, i.e., in the GHz range. Thus, it is suitable for its utilization in high frequency applications. In this study, the frequency domain parameters such as centre frequency, bandwidth and quality factor are a function of fractional orders $\\alpha$ and $\\beta$. This is evaluated mathematically, and has been shown using 3D plots by PYTHON programming.
Stability Analysis of Active Fractional-Order RC-Phase Shift Oscillator Arya Suman Pattnaik, Kumar Biswal, Sanjeeb Kumar Kar 2023 IEEE 3rd International Conference on Smart Technologies for Power Energy and Control Stpec 2023, 2023 Fractional order (FO) circuits and systems are an emerging field of study at present time. In this article, an active RC-Phase shift oscillator using an operational amplifier is used to demonstrate the application of an approximated RC symmetric fractional capacitor. Three fractional capacitors of various non-dependent orders are used in the FO RC-phase shift oscillator in this modelling to conduct the analysis. Along with the performance evaluation in the frequency and time domains, the responses' magnitude and phase are also analyzed. Later, in this study, steady-state step analysis is used to analyse the stability of the FO RC-phase shift oscillator.
Design Analysis and Stability Improvement of Fractional-Order Allpass and Bandstop Filters Kumar Biswal, Sumit Swain, Aakash Chakraborty, Yash Ranjan 2023 International Conference on Communication Circuits and Systems Ic3s 2023, 2023 In this study, a fractional-order (FO) allpass filter as well as a FO bandstop filter have been developed. The mathematical modelling of both the filters has been examined and upon analyzing its frequency domain characteristics, it showed similarity in properties at certain fractional-exponents of the elements. The frequency domain properties have been noted and the exponents providing the reciprocity in the frequency domain characteristics in both the filters have been noted. The stability criterion of the suggested filter has later been discussed in this paper. Here, the step response of the filters has been simulated in MATLAB and a mathematical time domain model has been examined in PYTHON software and 3D plots resulting in time-domain parameters corresponding to all possible outcomes of α and β values of the filters have been shown.
Modelling and Stability Analysis of a Fractional-Order RC Coupled BJT Amplifier Kumar Biswal, Sanjeeb Kumar Kar, Madhab Chandra Tripathy, Sumit Swain 2nd Odisha International Conference on Electrical Power Engineering Communication and Computing Technology Odicon 2022, 2022 In this paper the study of fractional-order BJT amplifier is depicted. The generalization of fractional capacitor in simulation model is initialized to study the characteristics of the proposed fractional-order amplifier. The simulation analysis of fractional-order BJT amplifier is conducted for both single and multistage structures. The entire analysis is based on realizing the fractional-order amplifier by making the use of mathematically realized fractional capacitor. The responses are characterized in MATLAB and Lab-VIEW software. Then the stability analysis is performed by initializing step response. This work uses the Python coding software to validate mathematically the stability criterion and plotting its 3-D responses.
