SummaryThe expected depletion of fossil fuels has brought in an increased demand for electric vehicles with better performance in terms of easiness of control and reliability of operation and hence is a fertile area of research. In the present scenario, motoring, regenerative braking, and charging operations are performed in electric vehicles by separate converters. In this paper, an integrated scheme is developed, wherein the same voltage source inverter is employed to obtain all the three modes of operation, which in turn reduces the number of switching devices. Further, a sensorless control used in the proposed scheme improves the operational reliability. This novel approach adopts a simple switching scheme for voltage source inverter to operate as a dual‐boost DC‐DC converter during the regenerative braking period. This switching scheme enables reconfiguring voltage source inverter to a dual‐boost rectifier in conjunction with a LLC resonant converter in the charging mode. A comparison is also provided between the performance of single switch boost and dual‐boost converters used for braking operation. The performance of a prototype brushless DC (BLDC) motor drive with Li‐ion battery pack is evaluated in motoring, regenerative braking, and battery charging modes. This paper presents a detailed design of the scheme, the simulation of which is done on a MATLAB/SIMULINK platform and validated experimentally.

“…To maintain the voltage of the DC bus as stable as constant as possible, an Energy Storage (ES) is usually connected. The technology of the ES depends on the applications [16]. For example, Supercapacitors can be used if it is required to deliver and absorb large amounts of electrical energy in short periods, making them ideal for applications that require high power bursts or rapid charging/discharging cycles [17].…”

This paper investigates the use of a Zeta converter in a micro mobility charging station. The system is supplied by a Photovoltaic (PV) panel and the energy is stored in a Li-Ion battery connected to a DC bus. Since the charging station is highly affected by the weather conditions, the performance of the system is evaluated under different irradiance levels and cell temperatures. In addition, the effects of parasitic resistances on the system efficiency are evaluated. The results highlight that the presence of parasitic resistances leads to higher ripples in the power output, indicating reduced efficiency and stability. Various irradiance profiles were applied to assess the system's performance, incorporating a battery load for practical relevance. The Perturb and Observe Maximum Power Point Tracking (MPPT) technique has been employed to optimize power generation. The entire study was simulated using MATLAB/Simulink, enabling a comprehensive evaluation of the PV system's behavior.
