As electric vehicles (EVs) are becoming more prevalent in the current scenario. One of the significant obstacles is range anxiety which hasn’t been overcome because of the short range of a single charge. By employing an on-the-spot dynamic charging system using a charged external battery pack, it can be avoided. In this manuscript, the control algorithms i.e. Proportional-Integral-Derivative controller (PID) are modelled by ensuring the electrical and thermal characteristics of the conversion are within a predetermined and acceptable range. The State-of-Charge (SOC), battery current, and battery voltage are observed and monitored in Matlab Simulink. To obtain the pragmatic results, a basic Battery Management System (BMS), which implements the Coulomb Counting method, is also developed and simulated. The semiconductor devices used are thermally modeled to measure dissipation. This is a suggested design for an emergency-only lightweight portable rapid charger. This design does not replace the standard charging stations.

This paper describes mathematical modeling techniques, simulation and implementation of boost converter. Four modeling techniques such as circuit modeling, mathematical circuitry modeling, and transfer function modeling and state-space modeling. Each modeling method is developed and implemented in MATLAB and Simulink environment. Circuit modelling is also done in PSIM tool. From the simulation results it is clear that capacitor voltage waveform which is a state variable gives identical response in all modeling techniques; state-space, mathematical circuitry, circuit and transfer function modeling approaches. Simulation results of all models perfectly overlapping each other and also settling time is very less in circuit modeling and transfer function modeling which is more desirable .Stability analysis ;bode plot ,pole-zero plot and step response are carried out using transfer function modeling .The offered models helps to the expansion of boost converter design, simulation ,analysis and educational tool[1].

This paper presents a comprehensive modeling, simulation and computational implementation of buck converter. Four modeling approaches of buck converter including mathematical, circuitry, transfer function and state space modeling are presented. Each modeling approach is demonstrated with various computational implementation methods including graphical, functional block and text based programming in MATLAB and Simulink environment. The modeling and simulation results for all four approaches are presented and the pros and cons of each modeling and implementation methods are discussed. It contributes to power electronic curriculum delivery that help students to gain complete view of modeling, simulation and computational implementation of buck converter at the perspective of circuit theory, differential equation, numerical method, control theory, s-domain, signal and system. The presented models also contribute to the development of buck converter design, simulation, analysis and education tool.
